Unless, I'm mistaken the idea of having parks in different locations is to get to the guests that otherwise would not make the trip to the original. It, in and of itself, is a clone. It is a realization that not everyone can necessarily got to the original. They can't get to the mountain, so they bring the mountain to them. I suppose on some level it's OK to have a few things unique to each park to entice the folks that might be able to do more than one experience, but, if you want to get to the most people, and get the most money, you have to supply the people with something to spend their money on, just business. You guys are trying to put a human emotion on a business's effort to simply make more money.
Again, Walt Disney hated repeating movies...he never said that in relation to his theme park(s). Even then he was talking about animated stories. (at the time, Pigs) He repeated, in kind, a lot of the nature movies through the years. How many ways can a beaver swim across a pond. And to say that he gave up on that principle because he cared about EPCOT and needed it because he lacked the funds for EPCOT. Well, that is partially true, but he would have been pretty hypocritical to all of a sudden decide that repeating was a bad thing unless, he knew that repeating that would make him a bucket load of cash. EPCOT was never in Walt's head as a Theme Park, it was going to be an actual city that, when built would be supported by the influx of tourist to see it. (MK) It was not a place that tourists would wonder through and rubber neck everyone like they do the Amish. It was meant as an upscale, technologically current, place to live, not visit.
