tip: don't use the snack vending machine. it's broken and eats up all dollar bills (worse than spearmint rhino).
This place charges adult prices for kids over 1 year old which is not right but otherwise i suppose it's worth it given the amount of play space they have (3 stories). My 18 month old daughter had lots of fun placing balls in the water area as well as the shoots. She played with everything she can get her hands on.
Would I be back? If I were to move to vegas, then yes. Otherwise, no.
