Before just throwing that out there I would encourage you to spend some time walking through how it would actually work. Do't just touch on the 35,000 foot view of where stations and routes would be, focus on how the guest would actually get from place to place using that system. What would a guest have to go through to get from point to point? What would happen when a train arrives at a park at park close and it's full and nobody can board (there would be a riot) because the park before it on the beam closed around the same time. How many stops and changes does it take go get from all the common point A to PoInt B scenarios? How long would it take a guest to get between the farthest points of the routes vs what it takes today (do this without hyperbole I the measurements).Mini Van, is expensive if used
I do not think it is that complicated. Take the monorail loop and route it south by the solar farm leaving Epcot to serve HS. From HS, continue west to AK, return back north and connect back to Epcot Mickey solar farm. That total loop will be less track than the loop added for Epcot and will service all 4 parks. And for the cost argument, again, refund the Gondola, Ferry Boat Dock, Roads/Bridges, etc.... Then the buses would serve Resort to Parks, monorail Park to Park. I just don't like how disjointed everything is, and again, everybody is more upset about the broken yeti, then spending hours on your vacation waiting for transport.
Its easy to throw things like that out there but it's vital that you clearly understand exactly how the guests would actually experience this. In most cases, history has taught me that the guest experience would be so confusing, difficult and slow that the value is just not there. While it may seem like it would be cool, it would not likely be a positive experience for the guests.
