Have you ever read about the ORIGINAL design which was, of course, much more elaborated and much longer than the built attraction? Don't get me wrong I love ToT, it's a major reason to go to DHS as many of the other attractions are dated (GMR) or boring (that car stunt show, I don't even care about the name). But again they downsized an attraction that could have been even better. Typical Eisnerian.
Eisner was the one that pushed to get ToT done. He was the one that suggested making it a resort that guests could stay in. It turned out to be unfeasible for a lot of reasons, but ToT was certainly no hatchet job. It was one of the most expensive attarctions ever built, and really pushed the envelope of what could be done.
