I agree with almost all your points
I'd rank DAK as less stagnant than DHS for a few reasons.
1) Every show in DHS needs to go, included the current form of Fantasmic. They're all extremely dated, they're all in bad repair, they're all comically of their time, and they all look tired. That's like... four attractions that need to be scraped, gutted, retooled from scratch. Nemo and Lion King aren't spring chickens but they are still serviceable. And, regardless how one feels about it, DAK just got Rivers of Light while Fantasmic has been trudging along for almost 20 years.
2). DAK (brilliantly) has animal trails and those will never be "dated" or "stagnant."
3). DHS will soon look like the shell of a theme park with a kids area (Toy Story) tacked on to one end and a Star Wars theme park tacked onto the other. There is nothing cohesive at DHS. It's a Frankenstein Monster of a park that's getting more and more deformed. The entire 2/3rds of the park that aren't Star Wars or Toy Story (and that aren't Tower of Terror) need a total re-do. Rockin Roller Coaster needs a new theme, Muppets (and I type this using a hand which is attached to an arm that has a Jim Henson tattoo on it) need to 100% revamp/do-over, Indiana Jones needs a ride (or two), and Sunset Blvd no longer fit with the theming of the park. It feels like three mini theme parks hodgepodge sewed together. DAK atleast feels whole.
DHS needs at least 15 rides total, EPCOT needs 20 rides total, DAK needs about 15 rides total.
Just my thoughts!
