While I agree a lot of it is hype, & doesn't seem practical (especially People Mover), but a monorail would be very fitting from Toy Story (3rd Gate & Hotel), to the new Parking lot across Harbor, & connected to somewhere near the current Monorail in Downtown Disney.
WDW has them going pretty long distances, and this one would have to be similar where it isn't ticketed transportation, but would have to try to keep the public from using it. lol
It would cost them a fortune. There were reports back in 2013 that a new monorail segment runs $100 million per mile in Florida where they (up until Bob Chapek) controlled the land, zoning and safety regulations.
Adjusted for inflation that's over $250 million per mile now. It's going to be even more expensive in California.
Plus, the trains run around ~$10 million per train. Walt Disney World is still waiting on new trains that were due to be replaced in the early 2000's.
The Disneyland monorail is an attraction only. It wasn't built to transportation standards like the monorail at Walt Disney World. It doesn't have air conditioner, runs limited hours and only has two stations. It's not a practical transportation solution for DLR.
As for the PeopleMover, WED has only ever built
one real PeopleMover in the Houston airport of all places. It's been promised over and over again—from the original EPCOT plans to the themed hotel areas of the Magic Kingdom. Yet, they never built it. The two attraction PeopleMover's they did build were not built to transportation standards either.
I get it. I love nostalgia too, but I see plans like this and shake my head. It's all a manipulation game to get control of zoning.
Do I think they'll do things like build attractions around the two other hotels? Yes, eventually. They don't have a choice if they want to grow.
