There's been a lot of discussion about what California Adventure needs next.
Disneyland has six water-based attractions I can think of (NOT including traffic on Rivers of America). In my opinion, California Adventure desperately needs some more water-based attractions to create the rich variety expected of a world-class theme park. Plus, in So. Cal., water means cooling off when the sun is blazing.
What type of water-based attractions would make sense at California Adventure given the expansion areas available, themes that would make sense at DCA and not duplicate what's already at DLP?
Or, is there some operational reason that Disney would no longer build an immersive water-based attraction like It's a Small World, Pirates, Splash Mountain, Jungle Cruise, etc.?
