It's 31.76 per person. No discount even if you make the room private. And no kids younger then 12 for parties.
When I had my daughter's birthday it was about $30/kid with fees and taxes, maybe a little less. If you want a private party where you're not sharing the room experience with others its a minimum of 10 and you have to pay up front. The party room after where you can do cake and presents is extra, around $70-75 extra.
