OK watched the whole thing and have a couple minor point and one big one:
Minor points:
- Country Bear Jamboree was actually popular in 1971, and not just because it was labeled an "E" ticket. That's why the show got two theaters for Disneyland and Tokyo Disneyland. It was assumed it would be just as much so in those parks (which turned out not to be the case in California). The Mickey Mouse Revue, also an E-ticket upon opening, never was as much. That's why it got demoted to a D ticket and closed after 9 years. The opposite happened with Hall of Presidents. It got upgraded to an E in response to demand.
- A minor nitpick: Per Martin's video, 20,000 Leagues was intended to operate up to 1,900 an hour with 9 subs, but could never hit that due to the time it took to load/unload the subs. The point in the video about capacity not meeting demand remains true.
BIG point:
- In the solutions section, it's never suggested to add minor attractions to help spread out demand and increase overall park capacity without significantly inflating overall park attendance. This is what Euro Disneyland did prior to opening. There was concern that there wasn't going to be enough rides, so a project was greenlit to increase park capacity by something like 10,000 people an hour by building several smaller rides that would open within 2 years of the park. That's how we got the Indiana Jones coaster, the Casey Jr. Train, Storybookland boats, Nautilus walkthrough, Old Mill Ferris wheel etc. A similar strategy could be used for WDW's parks, except the cost to do so would greater than it was in the 90s because Disney is now incapable of getting the same value out of their spending. They wouldn't cost $450 million a piece though.
