What Does a Kids Birthday Party Cost in London, Ontario? (What's Actually Included)
You are not alone if the birthday spreadsheet has three tabs and a headache.
"How much does a kids birthday party cost in London Ontario?" is one of the most common searches we see — and one of the most common phone questions after "are you open today?" Parents are not just hunting for the lowest number. They want to know what that number actually buys: play time, room time, food, adults, tax, and the stuff that shows up as a surprise on party day.
We host a lot of birthdays at Off The Wall Kids in East London (539 First St, Argyle, near Fanshawe College). This is our straight guide to party budgeting in London — what to compare, what we include, and how our food credit works. Live package pricing always lives on our birthday page so numbers stay accurate:

What parents are really comparing
Headline package price is only one line on the mental budget. Before you book anywhere in London, ask:
How long can kids actually play? Is the party room private, and for how long? How many adults are free — and what happens if Grandma and both parents stay? Is food included, fixed, or "credit toward our kitchen"? Is tax added at checkout? Do you pay everything when you book, or a deposit plus balance? Are socks, waivers, or gratuity extra?
Different venues answer those differently. A $275 headline can grow once HST, extra adults, and a mandatory gratuity land. Another package at $299 might include twelve free adults and unlimited play until close.
We will not rank every venue in London — that is your Pinterest board, not our blog. We will explain how we price parties so you can compare fairly.
Off The Wall Kids party packages (what the price covers)
Current tiers — 12 kids, 24 kids, 36 kids, plus private facility rental — are on the birthday page with up-to-date pricing. Every standard package includes:
Private party room for 90 minutes (2 hours for private rental) Unlimited Play Until We Close for your guests — online party bookings guarantee two hours from your booked start time Free adult admission per package (12 free adults on the 12-kid package, 24 on the 24-kid package, 36 on the 36-kid package) Food credit for our concession — you choose what to order from our kitchen, not a fixed "you get exactly this menu" box
That food credit model is the thing parents ask about most after price. Your package includes a credit (for example, $50 on the 12-kid tier). You order pizza, platters, and more from our kitchen. The credit comes off when you pay the food balance at the end of your party. Order more than the credit covers? You pay the difference on party day.

When you pay (and what tax looks like)
Book your party date and package through Bookeo: bookeo.com/off_the_wall_bookings
Package prices on our website are before tax. Bookeo shows the full checkout total including tax before you confirm — always check that number before you pay.
Party food is usually pre-ordered. Our coordinator reaches out the week before to confirm. Any food balance beyond your package credit is paid at the end of your party. We accept cash, credit, and debit at the facility.
We do not advertise pay-later or Klarna-style plans for parties. If flexible payment matters to you, confirm checkout options on Bookeo when you book.
"We only have eight kids — is the twelve-kid package worth it?"
Our entry package covers up to twelve kids. There is no separate eight-kid tier.
Families with six to eight guests still book it because the package is built around the whole experience: private room, unlimited play, twelve free adults, and kitchen food credit. At many venues, smaller guest counts come with tighter adult limits, shorter play windows, or per-adult fees. Here, parents and grandparents in your headcount are not an extra admission line item up to your package limit.
If your guest list is truly tiny, a gymnastics or activity studio with an eight-child minimum might fit better. If you want a full indoor playground with room for littles to run and adults to breathe, compare what is included — not just the smallest headline price in the city.
Best value vs "cheapest party in London"
We will say best value.
London has everything from rec-centre room rentals to trampoline parks and museum packages. Some entry prices look lower for eight kids at an activity-specific venue. Full indoor playground parties with private rooms tend to cluster around a few hundred dollars for a dozen kids once you add food and adults.
We are not the biggest party venue in Ontario, and we are not trying to win a "cheapest" headline. London families have voted us Best Indoor Playground two years running through community votes — we are grateful for that. Come for the experience, compare packages fairly, and book where the included stuff matches what your family actually needs.
What you might also budget for
Beyond the package and food balance:
Balloons and extras (available at the facility — ask when you book) Outside cake or cupcakes from an inspected bakery — allowed in your booked party room only, with a receipt Socks for anyone past the admission counter (we sell grip socks at the counter if you forget) Guests beyond your package kid or adult limits — ask when you book
Weekend slots in London fill fast. About four weeks out, the best Saturday times are often gone. Book early, confirm food the week before, sign waivers online before you arrive: offthewallkids.ca/waiver
