Before he died in 1966, Walt Disney described Walt Disney World as being different from Disneyland. Guests would not only have the chance to visit Cinderella Castle, but they would also be able to experience one-of-a-kind attractions that could only be found at this new place.
When it eventually did open to the world in 1971, The Magic Kingdom at Walt Disney World, unfortunately, had duplicates of most of the attractions with which guests were already familiar through the original Disneyland, so the new kingdom really wasn't very different at all.
Under Michael Eisner and Paul Pressler over the last decade, the situation worsened as more and more attractions were duplicated in order to realize cost savings that have proved elusive in most cases. In the process, Disney's five international travel destinations cannibalized each other's business and cheapened The Magic Kingdoms of Disneyland, as a whole.
In order to reverse this problem and in order to better differentiate The Magic Kingdoms from each other, one-of-a-kind, exclusive attractions should replace some of the existing duplicates.
First, which duplicates are the weakest and, as such, justify their own closures? And, second, what new stories and shows can be developed to replace these attractions and, thereby, draw more guests from around the world? (Ride systems and other expensive and permanent fixtures can be retained and used in different contexts while all other show equipment can be consolidated for use at the remaining version of each attraction.)
The objective is to create exclusive attractions that can persuade people to travel greater distances and to do so more frequently.
