Love this place ! I always get a good deal through group-on! They give you 6 wristbands, and lets say you checkout Sunday you can still stay and use the water area even though you turned room key in. My kids love this place more than any theme park in Los Angels.
Its a low key way for kids to play in the water. Its a good introduction to water play and good for kids who arent yet ready for a full-blown water park. Its also free.
