What is there to do for children under 42"

There's the arcade. Little kids area which is fun and a nice wave pool. There is also a nice a lazy river.

There's also a game room

There are plenty of other areas for small children.

Not alot but it's still fun to go, you have the wave pool, little kid area. I go and I have 3 kids.1,3 and 4 year old and they have fun.
