I don't think these are mutually exclusive positions to have ... a) world show case does seem different, like its not really the place for rides (I don't really care, but I can see how some people would think this, and maelstrom was already there)
b) I think a lot of people are upset that rather than adding a new ride, they are just taking one away to replace it with another. So nothing is actually gained by bringing frozen to Norway.
c) You also are talking about how things are, now. Right now, closing Soarin, REALLY has am impact on how much there is for kids to do. Its one of 2 major attractions at EPCOT ... 1/2 the majors. This means its not only going to offer less for kids to do, but it also means doing the other major, test track, is going to require a massive wait, its going to be flooded by people no longer doing Soarin.
