The first time I ever watched The Mummy was at Cabana Bay's pool! But Six Flags is not Universal or Disney. But all you really need is a projector and a projector screen, so it is a possibility. I've been to some small indoor water parks and even they have movies playing in the wave pool. Should KI do it? Yes. Could KI do it? Yes. Will they do it? Probably not. If they can't have all of the lights that are on the Christmas train at KI lit, how are they going to put a movie on in the wave pool? Cool idea though, I think this would be really cool!
