The only reason Disney can continue to get away with this is because of Uni's land problem, and also maybe because they're afraid to refurb/close down attractions for any extended period of time. I'll be honest, I used to be a bigger Disney fan than I am now, and while Disney World is still my favorite place in the world, it's sad to see them spending hundreds of millions of dollars building Fantasyland and Avatarland when we've got extremely outdated attractions like Universe of Energy and horrible attractions like Stitch dotting the landscape of the parks, with no attention from TDO. Maybe Uni's land restrictions are a good thing, it encourages to really treasure what they have and keep their stuff up to date and maintained.
