How much does a kids venue party cost? A 16-guest example (2026)
For example, a paid kids’ venue birthday (gym, pizza arcade, or activity center) for 16 guests typically costs about $730 all-in ($46 per guest), including Extra buffer.
That total is about $450 for the venue package, $50 for the extra adult food, $40 for the cake, $60 for the party favors, $70 for the party-host tip, and $60 for Extra buffer.
Extra buffer is spare money on top if something runs over. It is already inside that $730. This example is a paid kids’ venue birthday (gym, pizza arcade, or activity center). It is not a home birthday, and it is not an adult milestone party.
