Wow, some great ideas! I like the south seas. I come from a cold climate and it would be great to combine disney with that feel.
My favorite

the prince & princess idea, all the cm's dressed to the part. It would be a classic and only makes sense for disney to have it

My kids would love it and I would too
Last month I was in Las Vegas and when I toured the hotels I was thinking how great some of the ideas would be for
DVC resorts.
Paris themed, french-europeon feel, Paris -most romantic city in the world, 'Parisian' decor and a replica Eiffel Tower
Venetian, complete with canals, gondolas, and strolling performers
NYNY, replicates New York's skyline, landmarks, sights, sounds, and tastes. In addition to mock skyscrapers, the hotel's exterior features replicas of the Statue of Liberty and the Brooklyn Bridge.
