Additional Guests at Your Birthday Party — What Happens When You Go Over Your Package Count (Off The Wall Kids London)

You booked the Classic package (up to 10 kids). The RSVP list now says nineteen. Three grandparents texted "we're coming too."

This is what happens when guest counts grow past your package at Off The Wall Kids (539 First St, East London, Argyle near Fanshawe College) — extra kids, extra adults, billing, chairs, food, and the decision you should make before party day.

"Everyone past admission counts"

Your package includes fixed allotments for kids and free adults / non-walking babies. Every person who crosses admission counts — playing or not.

Two patterns we see constantly:

1. Whole-class invites — sometimes 30 kids RSVP and most actually show. 2. Young birthday kids — fewer kid friends but every adult the child knows arrives.

Both are workable. Both need a plan.

"Free adults per tier"

- Classic package (up to 10 kids): 10 free adults - Super package (up to 20 kids): 20 free adults - Ultimate package (up to 30 kids): 30 free adults

Parents and grandparents within your free adult count do not pay separate admission.

"Beyond your package — who pays?"

Additional kids (ages 2–17), adults, non-walking babies, and children 0–23 months beyond your package pay general admission at the front gate and are added to the final party bill — unless you arranged otherwise.

Decide before party day using the online guest list portal. Party parents can specify whether the host covers extra guests or whether extras pay individually at admission. That way nobody is surprised at the counter.

"Non-walking babies"

A non-moving baby (stays in a car seat the whole visit) has specific counting rules. A child who crawls or walks out of a car seat is charged at the 0–23 month admission rate.

Babies count toward your guest list. Sometimes staff can shift a baby to an adult seat if you are under on adults but maxed on kids.

"18 chairs — plan for it"

Each party room has 18 chairs. Setup is prepared for your booked package count, not unlimited extras. Additional guests may need to stand. We cannot pull chairs from other party rooms or the eating area.

If you expect a crowd, book the Super or Ultimate package up front — or ask if a larger room is available when you book.

"Siblings and extra kids — who decides?"

If a sibling or extra child attends, the party parent chooses whether to pay for them as part of the package or have their own parent pay admission. We do not police who is allowed emotionally into the celebration — but party room space and package counts are real limits.

"Billing — who actually shows up"

We bill for the kids who actually attend — with an important caveat: packages are priced up to 10, 20, or 30 kids. If you book the Classic package (up to 10 kids) and only eight arrive, you are still in the Classic package (up to 10 kids) price bracket. If fourteen RSVP and fourteen show, you pay for the package plus two additional kids at admission rates.

Same logic the other direction: large RSVPs with smaller turnout still sit inside the package you purchased.

"No sticker shock on admission"

Extras pay regular admission prices by age — the same rates on our admission page, not a surprise penalty fee: Admission & Pricing

"included party food bundles and ordering more"

Your package included party food bundles is the same amount regardless of how many guests actually eat. Food is usually finalized before party day, but staff review your order when you arrive — you can add or remove items before the kitchen fires your meal.

Need more food during the party? Tell us — we will get it going as fast as we can. Be aware parties are often spaced 30 minutes apart and food prep can take 30 minutes, so timing can be tight when the kitchen is between party orders.

"Upgrade if you can"

If your guest list grows early, ask about upgrading from 12 → 24 → 36 while space exists. Upgrading beats a stack of à la carte admissions on party day.

After the room time, everyone still gets the full facility — donut slide, ballistics arena, ninja course — for things to do in London until we close.

Overflow rapid-fire

Extra kid beyond package? General admission on final bill unless guest pays at gate — you choose on guest list. Extra adult beyond free count? Same. Only 18 chairs? Yes — book bigger package if you need capacity. Do food bundles grow with headcount? No — order more if needed. Bill for RSVPs or attendees? Attendees — but package minimum is the tier you booked.
