Actually the price is 15 dollars per child. The rest is true. Also, the entrance fee is for all day until closing at 10pm. Take some slippers if you don't like walking in your socks.
Kids are $10 each, 2 adults per child are free, additional adults $5 each. Make sure you do a waiver for each person prior to going to save time. Otherwise you have to do it there before the kids can play.
