I for one think Disney should have done this sooner. One of the few disappointments I've felt about WDW concerns the hotels. I mean...they're so...not Disney. The Grand Floridian, the Port Orleans, the Coronado Springs...they're nice hotels, no doubt about it, but they'd fit in well with ANY park, including Universal. Where are the little Disney touches that would make them special? I've been to Port Orleans Riverside, very nice BUT rather...ordinary. Not especially magical. I've been to the Pop Century, and it was kinda fun in a tacky sort of way, but again...not very magical. Coronado Springs, lovely...but not magical. Not in a Disney way.
But these new rooms are AWESOME. They are very Disney and exactly what one would want when staying on-site at a Disney park. I love them!!!! I would pay extra to stay in them, as long as the cost wasn't TOO exorbitant.
My suggestion for a Disney room: One based on The Twilight Zone Tower of Terror. A pink art-deco style room with a window that flashes (lightning, with a thunder crash) when you push a button. Perhaps the plaster around the window could be blackened, as if lightning-struck. Cool. And maybe a room based on Snow White, that would look like the Dwarf's cottage, with ceiling beams and a cuckoo clock. And a talking mirror! Coolness!!!!
Having been to WDW four times, I haven't really felt a yen to return. But those awesome rooms just might lure me back...
