If you like water parks, your best bet is to go somewhere else. If there weather is nice, try Surfin' Safari at nearby Holiday World. If the weather is bad, stay home.
The rooms are about $400/night, the water is cold, and several rides (2 slides and 2 pools) are closed, overcrowding the other rides and pools. There are too many rules, no water socks, no towels outside the water park and the wave pool is really wimpy. There are no dry towels available when the water park closes, room service won't answer the phone and the restaurant staff is too busy socializing to help customers.
They use a new key technology that works only intermittently. I had to go to the front desk twice to get a working "key". They kept telling me the one I had worked just fine (even after they replaced it.)
On top of everything else, you cannot charge things to room if you pay with a debit card.
