Saying yes to custom party themes without losing money
Unicorns, superheroes, a favourite show: a theme add-on at a set price, what it includes, what you won't do, and policy wording to copy.

The call comes in on a Tuesday. The party is in three weeks, and could it be unicorns? Not just a unicorn cake: unicorn plates, a rainbow balloon arch, a unicorn craft, and could the host maybe wear a horn? The parent is excited, the birthday child is turning five, and whoever answers the phone says "Sure, we can do that" before anyone has thought about who's buying the balloons.
Theme requests aren't the problem. They're a sign a parent cares about the party, and they're money you can earn. The problem is saying yes for free, one request at a time, until every Saturday has three custom parties and your hosts are inflating balloons at 8:30 in the morning.
What a free theme really costs
Take one "small" request and put real numbers on it:
- Plates, napkins, a banner and two packs of balloons in the theme: about $25.
- The host's extra setup, 40 minutes at $20 an hour: about $13.
- The back-and-forth: four texts with the parent, a trip to the party store, someone finding the glue gun. Call it 30 minutes of your time.
That's close to $40 and half an hour of yours, given away on a party that might earn you $120 after the room, the host and the pizza. Do it for three parties a weekend and you've handed back a good share of your margin, with nothing to show for it but a tired host.
One theme add-on, at one price
The fix is to stop treating each theme as a favour and sell it as a thing: a theme add-on, with a set price and a set list of what's in it.
A theme add-on that works for most venues:
- A tablecloth, plates, cups and napkins in the theme.
- A banner over the party table and a dozen balloons in two colours.
- One themed activity the host already knows: a superhero obstacle course, a unicorn colouring craft, a dinosaur dig in the sand table.
- Price: $45 to $60, depending on what your parties sell for.
Work it out once. If supplies cost $18 and the host needs 15 extra minutes (about $5), a $45 add-on leaves you $22. That's real money for something parents were going to ask for anyway.
Then make it fast. Pick the five or six themes you hear most and build a labelled bin for each: the bunting, the centrepiece and the table runner you reuse every time, plus a list of the disposables to restock. When a parent books "dinosaurs", the host grabs the dinosaur bin. No shopping, no guessing.
For everything else, offer a colour theme: the parent picks two colours, and you do the table, the balloons and the banner in those. It covers the favourite show you've never heard of, without promising characters you can't deliver.
What it includes, and what you won't do
Most of the trouble comes from what wasn't said. Write it down once, put it on your party page and in the booking confirmation, and point to it every time.
Wording you can adapt:
Theme add-on, $45. Choose a theme from our list, or any two colours. It includes a themed tablecloth, plates, cups and napkins, a banner, a dozen balloons and one themed activity led by your host.
You're welcome to bring extra decorations that stand on the table. We don't put anything on the walls with tape or tacks, and we don't allow confetti or glitter (they end up in the equipment for weeks).
We can't print characters from shows or films on our own signs. Licensed plates and napkins from a party store are fine, and you can bring them.
Please choose your theme when you book, or by the time your final count is due. We can't change it after that.
Adjust the rules to your space. A gymnastics gym says no to confetti because it ends up in the foam pit. A play centre may say no helium balloons in the main play area. A pool says nothing goes in the water. Whatever your rules are, write the reason in a few words; parents follow a rule they understand.
Keep it off the host's morning
A theme should cost the host a few minutes, not their whole setup. Three habits keep it that way:
- Set a cut-off. The theme is chosen by the time the final count is due, a few days before the party. After that, the bin is packed and nothing changes. A parent who texts on Friday night asking to switch from dinosaurs to space gets a kind no.
- Fix the setup time. The host has the same 15 minutes to set up a themed table as a plain one. If a parent brings a balloon arch, they put it up themselves within the party's time, and it comes down with them.
- One person answers theme questions. Not the host, not whoever's at the desk. Questions go to the person who books parties, who answers from the written list.
And when a parent sends fourteen photos from the internet of a party they'd like recreated, here's a reply that keeps them happy and keeps you sane:
Those are gorgeous! Our space theme includes the table, the banner, balloons in navy and silver, and our rocket obstacle course, which the kids love. You're welcome to bring anything extra that stands on the table, and we'll make sure it's all set before your guests arrive.
Costumes and characters
The host-in-a-costume request comes up more than you'd think. Unless you've decided to sell a character visit as its own add-on, with a costume you own, cleaned and fitted, the answer is no. A host in a hot costume can't run a game, see the whole room or help a child off the climbing wall.
Some parents will book an outside performer instead. Decide your rule now: allowed with notice, within the party's time, with the performer checked in at the desk like anyone else. Saying it in writing ahead of time is much easier than saying it at the door.
In Caletan
A theme is an add-on on the party package. Priced for the party and counted, up to one, it's something the parent ticks when they book, and it's on their bill with everything else. Parents can add it from their party's page until the count locks, which is the same cut-off you'll want for the theme itself. The packages guide shows how to set one up, and birthday parties shows the rest.
