There is a third option:
Imagine the Walt Disney World Resort without all of the problems:
Four parks in clusters connected by innovative transportation.
A thriving city in the middle within walking distance to transportation hubs.
EPCOT Center built, but constantly 'plussed.'
A place where vacationers would arrive by car or plane, and never step foot in a bus or car or taxi again. And never leave the property until the vacation is over.
Who says Walt couldn't have done a better job at developing the project than Ei$ner? Let's take 'em a step at a time:
We know he liked to create innovative transportation. We can see by his original layout of the MK that he had an innate understanding of traffic flow. Why couldn't he have carried that through to the whole park? What makes the guy who greenlighted Happy Days more of an expert than Walt?
Ei$ner greenlighted Celebration, but stuck it way far away from the parks, exactly opposite to what Walt wanted. Maybe DB is right, maybe the 'city' concept was a red herring to get the legislature to approve it. Or maybe he is the original Andre Duany, a guy who incorporates TNDs INTO the resort complex. Meaning executives, workers, and permanent residents become the 'guinea pigs' for Walt's ideas on making a better tomorrow. Are you saying the implementation of Celebration could not have been improved?
On EPCOT Center, the concept of corporations showcasing their latest innovations was done, albeit in a *******ized sort of way. But who is to say that Walt would not have been happy with the outcome, or that he wouldn't have fixed some of the problems: putting the weenie at the front of the park, hugeness of FW, the layout of the WS, the destruction of show with the Swalphin.
Finally, we know that Walt hated what happened to Anaheim. It is a farce to think that once he saw the potential of creating a vacation destination, that he wouldn't have tried to improve upon his original model. Heck, THAT's WHY he bought 47 square miles, remember? To have enough to implement everything his imagineers could dream up. What makes you think that Ron and Card and Cou$in Mikey could do a better job of inspiring the imagineers to create a seamless vacation resort where passengers are flown in, whisked to their hotel (conveniently next to one of their favorite parks), and conveniently sped to each park and shopping district by magical transportation.
Its all speculation both ways, but mine is more plausible.
