Looked through this thread but not going to respond to everything since lots of it is crazy talk.
while it would be great to have some type of fixed transit connecting all the parks, I dont think expanding the current monorail system is the right thing to do or the best use of funds.
personally I'd vote for some type of PRT system like at london hethrow, a system like that would be able to provide direct point to point transit without connections and would be able to be expanded as new resorts/destinations are created
they could even do it as a "premium" transit system and charge extra for it possibly.
if they simply wanted to make a train system i think an elevated/ground level light rail type system would be best especially for connecting to animal kingdom or a combination of lightT/PRT would be amazing
connect groups of resorts together with PRT and different TTC hubs and connect the hubs with a mass transit light rail system, thus enabling anyone to get from anywhere to anywhere without a bus
the trick to getting anything at all built though would be to come up with a plan that could be built in stages, and have the first stage or two provide alot of tangible benefit.
while it all sounds cool, i just dont see it ever happening, since people aren't canceling trips to wdw due to traffic etc, as long as ticket sales are high nothing will change
and while the monorail is "cool" or perceived to be, alot it benefits from the "novelty" factor alot
it would have been smart to incorporate mass transit from the get go, but unfortunately disneys been on the bus kick for over 30 years now, so its really hard to change the mindset
