Please...you can have Fantasmic. Never was impressed with that anyway, never asked for it, just got it. As for DLR, been there, done that, not worth the 6 hour plane ride in my opinion. I'm glad I did it once but if it's written someplace on my future itineraries, it's so far down I can't see it.
Saying there shouldn't be "clones" would certainly punch a lot of holes in our economy. Only one McDonalds, Burger King, Outback, Olive Garden, Sears, J.C. Penny's, only one mall, only one movie theater able to show the same movie on the east coast at the same time as one is playing on the west coast. The mere fact that there are multiple Disney Parks sorta throws that "no clone" out the window all by itself. Disneyland is an entity as a grouping of theme park attractions, it doesn't matter what the attractions are or were, Disneyland is unique. Then Walt himself, decided to clone the thing on the east coast. Why...if the east coasters wanted a Disneyland, why didn't they just go to California and see it?
