If I decide to throw her party here, the 10 people it says can come in for all the rides and buffet, will it include us?? Or do her father and i to be part of the ten? How does that work?

Hi! All party packages include 10 players and then 2 additional buffet-only admissions for the adults

You can pay for the buffet by itself without doing the rides or arcade.

Parents are part of the ten.

I believe you have to be part of the ten or just watch the kids while they get on the rides. I just put my kids on the rides and watch them so it's cheaper.
