Count me down as pro-Eisner. Yeah, his last ten years had many, many failures and his reign almost ended with the company being carved up in a takeover like the one he was brought onboard to stop in the 80's, BUT...
I think he avoided one big problem that would have been permanent for WDW, while most of the problems he left have been turned around or could be turned around with the right leader. I agree with most of what's been said about the drive for constantly increasing profits; I think that's his biggest negative legacy. His biggest positive legacy is the horizontal expansion in the tourism industry: if there's money to be made, Disney should be the ones making it. It got us the vastly improved food, the cruise line and the amazing lineup of hotels we have today.
Disney was not really in the hotel business when Eisner started with the company. The Disneyland Hotel was still owned by Wrather. The Poly and Contemporary were supposed to be owned by U.S. Steel; they were bought out by Roy Disney only when construction fell behind. The company had lost its appetite for operating the few hotels they had. This is evident from the deal with Tishman that eventually resulted in the Swan and Dolphin. Instead of pushing forward with more experiences like the Poly or Contemporary run by Disney, there were going to be some nondescript hotels from an outside company. Eisner couldn't get out of the deal, and the compromise was eventually hotels that Disney still had creative control over, at least. After Eisner comes, BOOM. Grand Flo, Caribbean Beach, Wilderness Lodge, Yacht & Beach, etc. EVERY resort (depending on how you define Art of Animation) except Poly, Contemporary, and Ft. Wilderness came from Eisner's direction. All new rooms since he left have been expansions. Simply put, without Eisner, we could have seen the property littered with boring box hotels like Walt hated about Disneyland or even had the parks sold off back in the 80's. That kinda stuff you can't recover from. Stuff like a cheap, misguided DCA? Sure, it was bad at the beginning, but after just twelve years it will be transformed into a worthy neighbor to the best theme park in the world. The bad DCA will be a small footnote in the history of Disneyland.
Re: Dinoland. I've heard the choice between Dinoland and Beastly Kingdom came down to "kids like dinosaurs" rather than the movie tie-in. If the movie tie-in was the goal from the beginning, Countdown to Extinction would've opened as Dinosaur!
