Rebuilding the parks is not what I was implying. I really don't have a problem with the same rides in other parks so long as they have a touch of individualism to them. I would be disappointed if the rides were identical or "clones" but as for what they have done in the past, I don't mind it. It would be better, in my opinion, if Soarin eventually had a different movie than Cali's version.
But on the other hand, there are a lot of people who do visit more than one park and do so because they offer different rides. Where's the economic sense in not making the parks different in an attempt to draw visitors who have been to a park already. If the parks are the same, you'll draw regional visitors. If the parks offer differences, so long as duplicate rides have a sense of individualism, you'll attract the same regional guests but will also draw visitors from outside of the region. I would never have gone to Disneyland Paris if it just had the same rides as WDW. Likewise, I would have no desire to go to Disneyland if it was the same as WDW. Simply put, you expand your park market globally by offering exclusively individal rides in each park where as identical parks limit your market to only regional. There's some economic sense. Just my opinion..
