Bouncin Bonkers in Cresthill can give you the entire place if you have that many people. We had a big family party there with 50 people (only 20 kids). I sent my parents,aunts ,older folks with no kids to Brickhouse Pizza next door when we had pizza for the kids. It was a little more civilized for the elders that way! Then they all came back for cake etc.Also we extended the party an hour for $50. It was worth it!Good luck!
