Why won’t Disney add monorail so that all four parks are connected? They can certainly afford it!
They can’t afford to keep the ones they have running consistently.
Yeah, I wouldn’t be keen on adding more monorail to the system. But a light rail (on-ground) system might be feasible. I just don’t see it happening unless the cost of buses skyrockets in comparison - busses are cheaper and much easier to re-allocate to handle peak traffic.
If we’re going back to the ideal of adopting/showcasing possible future tech (that is, getting the “wow” factor past the bean counters), some kind of PRT system would be the way to go - small-cacpity autonomous train vehicles that use offline stations so that through traffic isn’t held up by start/stop cycles. You get the re-allocation problem fixed because empty vehicles can be shifted toward particular stations in real time, and the total number of stations wouldn’t need to be very large (one per park -two at Epcot perhaps - and ideally one per resort).
But that has drawbacks - it’s experimental still, the initial costs are high, and regulatory issues are still a wild-card (specifically related to the required gap between autonomous vehicles and its effect on capacity).
Now this is a conversation I would enjoy listening to.
