If you are referring to me, that's not what I said (or meant), at all.
My point was, IPs ARE NOT needed at water parks. People are either going to go or they aren't. Simple as that. Fill the place up with great theming and come p with some original story for it and you're all set. IPs add very little appeal to water parks. Even if you like the IP, if you don't like water parks than what good is it to you?
IPs need like Frozen need to be put to use where they are accessible to all people. Not all people like water parks, not all people can SWIM. It's just a waste to use such a giant IP at a water park imo. It's a waste to use any IP really.
