Joe Rohde was certainly concerned about the lack of attractions & entertainment at the AK's opening and his concerns were validated when the public response to the AK was lackluster. People attend theme parks for the attractions and entertainment. The AK may have been a beautiful, glorified zoo but few people are interested in spending several hundred dollars to spend the day at a zoo.
I realize that Disney fanatics get a warm & fuzzy feeling that makes even walking around the parks worth the price of admission, but recognize that you're outliers. A trip to WDW is a huge investment for the typical guest and they're not looking for a "walk in the park."
This is a ridiculous statement. Let's use a non-Disney analogy: Last Holiday season, my family stayed at an all-inclusive in Los Cabo. Because it was the Holidays, I anticipated it'd be crowded -- and it was, but the resort was enormous and could easily handle the crowd. However, the facilities could not. This was best exemplified by the dining -- reservations were filled by its vacation club members, limiting us to the buffet, which was quite good but the resort couldn't keep up with its guests so section was very limited. Beautiful resort, but we didn't pay nearly $700/night to enjoy the grounds.
I have several pictures of the MK's wait board (and a few of the Studio's) taken in the late 1990s that I'll scan and share later. 90-minute (and typically 120) were the norm for the Mountains, and 60+ was expected on the more popular attractions. You'd expect the MK to have longer waits today given the larger crowds, but that's not the case.
