Martial Arts Summer Camp Ideas: Sign-Ups and Parent Emails With AI

Settle the camp's facts first (ages, dates, hours, 20 places, price, adult-to-child ratio, pick-up rules), then have AI turn that one sheet into a week-by-week programme, kit list, sign-up page and a six-email parent sequence. Price from your costs: the worked example below breaks even at 16 of 20 places. You check every date, price and safety rule.

Martial arts summer camp ideas are easy to find, and the games on those lists are the easy part. What costs a school money and trust is the gap between documents: a sign-up page that says drop-off is 8:45, a confirmation email that says 8:30, and a pick-up rule that lives only in the head coach's memory. The fix is one fact sheet that every document copies from. AI drafts from it and cross-checks against it. It does not decide who may collect a child or how many children one coach can watch; those answers come from your insurer and your governing body.

One camp fact sheet that every page and email copies from

Fill in the table below before you ask any assistant for anything. The values belong to an illustrative school running four one-week camps for children; replace every one with your own.

Keep the sheet where every chat can see it. A Project in ChatGPT or Claude lets you store it once as standing instructions or a file, so each new conversation starts from the same facts. Without Projects, paste it at the top of every prompt.

Here is how it goes wrong without a sheet. You ask one chat for the sign-up page and another for the confirmation email. The page says drop-off is from 8:45. The email, filled in by the assistant from habit, says 8:30. Families arrive early while your first coach is still carrying mats in, and for fifteen minutes children are in a room with one adult. Neither document is wrong on its own. The fix is a rule: nothing leaves your desk until every date, time, price and number in it has been compared with the sheet. The dry-run section has a prompt that does the comparison.

Pricing 20 places: break-even first, then the fee

Choose a price after you know what a week costs. Split the costs into two kinds: fixed costs that arrive whether 8 or 20 children come, and per-place costs that grow with each booking. Illustrative fixed costs for one week:

Per-place costs come next: a camp t-shirt at $6, plus the card fee. Square's pricing page lists 3.3% plus 30 cents for online and invoice card payments on its free plan; check your own processor's figure. At a $199 fee that is $6.57 plus $0.30, so $6.87, and a total of $12.87 per place. Each booking therefore contributes $199 minus $12.87, or $186.13, towards the $2,800. Break-even is 2,800 divided by 186.13, which is 15.04, so you need 16 places because the fifteenth child still leaves you $8 short.

Price moves the break-even less than most owners expect, and fill rate moves the result far more. Break-even is 17 places at $179, 16 at $199 and 14 at $219. A $20 rise on a full week brings in about $400 extra; a $20 cut on the same week gives away about $400 you would have kept.

Discounts need the same arithmetic. An early-bird price of $179 on the first eight bookings gives away 8 × $20 = $160. A 10% second-child discount on four siblings gives away 4 × $19.90 = $79.60. That is roughly $240 against a full week's $923 margin, but against a 16-place week's $178 it turns a profit into a loss of about $62. Offer a discount only if it brings bookings forward, and write the rule on the fact sheet so it is applied the same way to every family.

Write a go or no-go rule before you advertise. Pick a date about three weeks before each week starts and a minimum number, which should not sit below your break-even unless you have decided to run that week at a loss as a marketing cost. At $199 that minimum is 16. If a week has 12 on that date you can merge it with a neighbouring week, offer places to the waitlist of a fuller week, or cancel and refund in full. Deciding now means you will not run a week at a loss out of embarrassment.

AI is useful for the scenario table, provided you make it show its working:

Fixed costs per week: $2,800. Per-place costs: $6 t-shirt plus a card fee of 3.3% of the price plus $0.30. For prices of $179, $199 and $219, give the break-even number of places and the profit or loss at 12, 16 and 20 places. Show the formula for each row and round break-even up to the next whole child.

Assistants slip on arithmetic in a predictable way: they forget the per-place costs, or round 15.04 down to 15 places. Rebuild three rows in a spreadsheet before you trust the table; the Google Sheets AI prompts tutorial covers prompts for formulas, so you can ask for them and keep the checking.

A four-week programme, day by day

Give each week a theme so families who book two or three weeks do not repeat themselves, and end every Friday with something parents can watch.

• Week 1, foundations: etiquette, stances, balance and a warm-up the children can repeat at home.
• Week 2, movement and agility: footwork patterns, obstacle circuits, reaction games, and basic falls and rolls on mats.
• Week 3, partners and respect: controlled partner drills, distance and timing with pads, and a personal-safety talk on saying no and telling a trusted adult.
• Week 4, show week: each group rehearses a three-minute demonstration for Friday at 14:30, with families invited.

Every week uses the same daily shape, which keeps staffing simple and lets parents learn the routine once:

Ask AI to fill the shape with specific activities, and tell it your constraints in the prompt, because it will not guess them:

Use the camp fact sheet and daily timetable below. Plan Week 1 (foundations) for 20 children aged 6 to 13 in two groups. For every block give one specific activity, the equipment needed, and a quieter swap for a wet or very hot day. No contact sparring. Keep to my timings.
[paste fact sheet and timetable]

A first draft usually looks plausible and contains three or four things you must change. In this illustrative output, the Wednesday partner block read "free sparring in pairs to practise timing", although the prompt said no contact sparring. The Thursday circuit ran 25 minutes of burpees and shuttle runs with no water break. And the 6 to 9 group had the same 70-minute skills block as the 10 to 13 group. The fixes: replace the sparring with a target-pad timing drill where one partner holds the pad; split the circuit into two 12-minute rounds with a water break between them; cut the younger group's skills block to 45 minutes and add a game at the end of it.

Ask for a bank of extra activities once the shape is right, then pick from it yourself:

• Warm-ups: stance tag, "sensei says", a ruler-drop reaction game, mirror drills in pairs.
• Skills: stance relays, a cone-weave and kick-target circuit, pattern-memory chains where each child adds one move.
• Values: an etiquette scavenger hunt (find the five dojo rules posted around the room), a belt-tying race, a story and a question.
• Quiet: three minutes of still breathing, designing a personal certificate, a drawing of "my best move".

Adapt the examples to your style. A grappling school would swap pad work for a breakfall circuit and partner positional drills; a striking school keeps the pads and moves falls to the quiet corner of week 2.

The kit list, before and after you add your own rules

A generic first pass reads: "Comfortable clothing, a water bottle, a packed lunch and a positive attitude." Parents cannot act on that. After you give the assistant your rules, the list becomes one that answers the questions you would otherwise get by text on Sunday night:

The prompt that gets this result: "Write the kit list as a two-column table. Each line has the item and one sentence a parent can act on. Use my fact sheet for the lunch, uniform, refill and phone rules. Do not add any item or rule that is not in the sheet." The last sentence matters, because assistants like to add "a towel" or "a snack for the afternoon" that nobody has agreed to.

Safeguarding and pick-up rules to settle before you advertise

These are decisions, not drafting jobs. Ask your insurer and your governing body what they require for children's holiday activities (staff suitability checks, ratios, first-aid cover, incident reporting), settle each point, then use AI to turn the decisions into plain wording. The safeguarding policy template for a children's club covers the longer document; the points below are the ones a camp needs in writing before the first booking.

• Two adults at all times. No adult is alone with a child. Use rooms with a window or an open door, and keep any one-to-one conversation in view of others.
• Ratio. Get the maximum for each age group from your insurer in writing, plan below it, and keep one floating adult so the two-adult rule holds when someone takes a child to first aid.
• Checks and briefing. Every adult, including volunteers and teenage helpers, has the checks your insurer or governing body requires and signs the code of conduct. Ask whether teenage helpers count towards the ratio. Brief the team at 8:30 each morning.
• First aid and incidents. A named first aider on site every day, a kit by the door, an incident book, and a rule that parents hear about any injury on the same day.
• Medication and allergies. Collected on the form, shown to every adult on a one-page list, and never put in group emails.
• Photos. Permission is asked at booking and the default is no. Only the camp's own device takes photos.
• Collection. Named adults, a family password, photo ID for anyone new, and a minimum age for collectors that you decide and state.
• Late collection. A ladder with times on it, shown below, and the promise that no child is ever sent home alone.

Give the assistant the decisions and ask for parent-facing wording. This is a filled-in version of the collection rules, illustrative and for your insurer to read before it goes live:

Children leave only with an adult named on their booking form. Every family has a password, which the collecting adult gives at the door. If you are sending someone new, add their name and relationship to your booking before the day and tell them the password; we will also ask for photo ID. If we do not know the person and the password does not match, we will keep your child with us and ring you and your emergency contact. Collection is 15:00 to 15:15. If your child is still here at 15:15 we will text you; at 15:30 we will ring you, then your emergency contact. Two coaches stay with any child who is waiting, and we never send a child home alone.

Rehearse the awkward case with the team: an unknown adult arrives, says they are an uncle, and has no password. The script is short. "I'm sorry, I can't release [child's first name] without the password. Let me ring their parent now." Say it aloud once in the team briefing, so no coach is improvising it for the first time at the door.

One trap deserves its own line. Assistants add sentences such as "this policy complies with all relevant regulations" or "a ratio of 1:8 is standard". Delete them. The assistant cannot know where you operate or what your insurer demands, and a reassuring sentence that nobody has verified is worse than none. The waiver for children and the conduct code for players and parents tutorials cover the paperwork that sits beside these rules.

The sign-up page and form: what to ask and where it lives

You have three realistic homes for the sign-up page. Pick the one that fits what you already run:

Whichever you choose, the page itself should carry the same facts in the same order every time. Ask the assistant to draft it from the fact sheet, then check that it contains these blocks:

1. A box at the top with dates, ages, hours, price and how many places are left.
2. The daily timetable, in the table above.
3. What is included in the fee, and the kit list.
4. A three-line safety summary: two adults at all times, a first aider on site, collection by password.
5. The refund rule and the date it changes.
6. A short answers section, then the booking button.

The form needs to ask enough to run the day safely and nothing more. Per child: first name and surname, date of birth, martial arts experience (used to group them, so ask for time trained rather than belt colour), medical conditions and allergies, any medication they carry, and photo permission as a yes or no. Per family: parent name, phone and email, a second emergency contact, and the authorised collectors with their relationship and the family password. Add a consent step that links to your waiver. Leave out anything you will not use; a home address, for instance, is rarely needed for a day camp.

Before publishing, make the assistant play a parent. It finds the gaps faster than your own re-reading, because you already know the answers:

Act as the parent of a 7-year-old who has never done martial arts. Read the sign-up page text below. List every question you would still have before paying, in the order you would ask them. Do not answer the questions.
[paste page text]

A typical illustrative result: "Is lunch provided? My child has never trained; will they be with beginners? Can I book three days instead of five? Is the camp t-shirt included? What is the latest I can collect? My younger child is 5; can they come?" The page had answered none of the first, second or last questions. The fixes were a short paragraph for first-timers, a line saying the minimum age is 6, and a sentence on lunch. The booking-by-the-day question became a decision: weeks only, and the page now says so.

Keep real children's details inside the sign-up tool. When you test prompts, use invented names. If you ever want an assistant to summarise the medical column, read the plan's data and training settings first, or do it by hand: a one-page list for the lead instructor takes about ten minutes and keeps sensitive details out of chats altogether.

Six parent emails, from booking to the Friday showcase

Draft each email from the fact sheet, one at a time, with its job and length stated:

Write email 3 (the Friday-before email) from the fact sheet below. 150 to 200 words. Plain and warm, no exclamation marks. Put the practical facts in a short list: drop-off window, which door, collection window, kit, lunch rule, camp mobile. Use [first name] for the parent and [child's first name] for the child. Mention no medical details.
[paste fact sheet]

This is the kind of draft you should get back, illustrative and trimmed:

Subject: Camp starts Monday: what to bring and where to go

Hi [first name], [child's first name] starts on Monday. Everything you need is below.

Drop-off is 8:45 to 9:00 at the side door. A coach will sign [child's first name] in. Collection is 15:00 to 15:15 at the same door; please bring your family's password, and photo ID if we have not met you before. Pack a named water bottle, a packed lunch in a named box (no sharing, nothing to heat), a spare t-shirt and socks, and leave phones and jewellery at home. The camp mobile on the day is [camp mobile number]. See you Monday. [your name]

Even a good draft needs a read against the sheet. In this one, the assistant had first added "there is free parking behind the hall", which nobody had said, and "dress comfortably", although the sheet asks for uniform or a plain t-shirt. The subject line had also come back as "Get ready for an awesome week!". The edit is to remove the parking line, replace the clothing line, and use the plain subject above. Here is the tone difference in one pair: before, "We are thrilled to welcome your little warrior!"; after, "Here is what to bring on Monday." Parents scanning on a phone at 7:30 want the second.

Two more messages are worth drafting now, while nothing is going wrong. The first is the same-day change note, for a hall problem, a power cut or a storm. Give it three lines: what has changed, what families need to do, and when you will next update them. For example: "Camp is moving to the community hall next door for today. Drop-off is at the same time, at the hall's front entrance. We will text again by 8:15 if anything else changes." The second is the waitlist message: "A place has come up for the week of [date]. Reply YES by [time] to keep it; after that it goes to the next family." Name the deadline in hours, so the place does not sit empty.

Send emails from your sign-up tool or email service to a list, and never as one email with everyone in the CC line. Send them from an address a person reads, so replies reach you, and keep the camp mobile for urgent matters on the day.

A dry run before bookings open

Run three checks before you publish anything. The first is the cross-check. Paste the fact sheet and all six documents into one prompt:

Below are my camp fact sheet and six documents (sign-up page, kit list, collection rules, and emails 1 to 3). List every date, time, price, number, phone number and rule that appears in the documents. Mark any that differs from the fact sheet or from another document. Present each difference as: document, what it says, what the sheet says.

On a typical draft set, this turns up two or three mismatches. An illustrative run found that the confirmation email said drop-off from 8:30 while the sheet said 8:45, that the kit list called the t-shirt "$6 extra" when the fee includes it, and that the page promised a refund up to seven days before when the sheet says fourteen. Each would have produced complaints on day one. Fix the documents, never the sheet, unless you have changed your mind about the rule itself.

The second check is a booking made like a parent would make it: on a phone, in a browser you do not normally use, paying with a real card for the cheapest week, then refunding it. Check that the confirmation arrives within a minute, that the 21st booking goes to the waitlist, and that the early-bird price switches off on the right date. The third check is a ten-minute team rehearsal of the unknown-adult scene and the late-collection ladder, with someone timing it.

Turning camp families into term students

The camp is also your best trial class: a week of the child showing up, and a parent who has watched a Friday showcase. Email 6 should invite them to a class without pressure. An illustrative version:

Subject: [child's first name]'s camp certificate, and a class if they want one

Hi [first name], thank you for sharing [child's first name] with us this week. Their certificate is attached. If they enjoyed it, we run beginners' classes on [days and times]; a first class is free and you are welcome to watch. Reply with the day that suits and I will save a place. [your name]

Put a "came to camp" column in the sheet where you track trial classes, so you can see later which weeks turned into members. A quick sum shows why this matters. Suppose a junior membership is $60 a month and the average student stays eight months, which is $480. Three camp families joining add up to $1,440, which is more than the $923 margin of a full week at the pricing above. Those are illustrative numbers; use your own retention figure, not mine. If replies turn into phone calls, the trial-class calls tutorial covers how to handle them.

Email the waitlist families first when you announce the next camp, since they already told you they wanted a place. Then keep the fact sheet. Next year's camp starts from the same document, with a new date column and the prices you learned to set.

Questions school owners ask before opening camp bookings

Can I paste children's details into an AI assistant?

Keep names, medical details and allergies out of chats. Draft with placeholders such as [child's first name], and leave the real details inside your sign-up tool or membership software, where parents entered them. If you want an assistant to summarise sensitive columns, read your plan's data and training settings first and ask your data-protection adviser. A hand-made one-page list for the lead instructor is safer.

How many children can one coach supervise?

No single figure fits every school. Your insurer and your governing body set the maximum for each age group, so get it in writing and plan below it. The worked example uses three adults for 20 children and a rule of never fewer than two adults with the group, but treat those as sums, not advice. Young groups, mixed ages and mat work often justify more adults.

When should I open bookings, and when should I close them?

Open once the programme, price and staffing are firm, ideally eight to ten weeks before the first day. Run an early-bird price until about six weeks out, then set a go or no-go date roughly three weeks before each week starts. Close sign-ups seven to ten days before, so the kit, rota and medical list can be finalised. These are planning habits, not rules.

What if only 12 families book a week?

At the worked example's numbers a 12-child week loses about $566, so decide the rule before you advertise. Your options are to merge it with a neighbouring week, offer the waitlist from another week a late place, or cancel and refund in full. Never cut below two adults or your insurer's ratio to save money. Tell families your decision on the go or no-go date.
