The only thing I'll say with regards to the recent discussion is this:
The past cannot and should not dictate the future. And this is even more true in the theme park business. So while any current and future park project should pay homage to the designs of the past, it should not be ruled by them. You have to design for the future, not the past. And while I know its sensitive because its "Walt's Park", Disneyland is no different, it has to move into the future. Because if a theme park, especially the worlds number one theme park company, doesn't design and change for the future they will lose customers long term. The world is changing, and so is consumers tastes and preferences in terms of theme park experiences. Nostalgia plays a big role right now because of the divisive world we currently live, but that won't last forever. As the next generations come up they aren't going to have the same nostalgic feelings as the generations of the past. As such the parks, how they are built, and the experiences contained within them have to change. The theme park design rule book written by Disney is not set in stone, its written in pencil so it can be changed in the future.
