re Florida routes;
Tri-Rail commuter trains currently cover West Palm to south of Miami Amtrak, using the same tracks and stations, as Amtrak, except that Amtrak Miami is a "dead end" station that Tri-Rail does not serve. All other Amtrak stops from West Palm south are both Amtrak and Tri-Rail station stops, and Tri-Rail has a number of additional station stops that Amtrak does NOT use as station stops. A JAX - West Palm (or JAX - MIA) Amtrak service using the FEC would be a very good thing to start, to serve the Florida east coast, connecting at West Palm with the Silver Service trains to/from MIA or to go all the way to MIA, and at JAX with Silver Service trains. It might also be enough to get Amtrak off it's "on the fence" position on NOL-JAX, suspended after the hurricane hit NOL, and would provide expedited MIA-NOL service compared to having the JAX connection with current Silver Service trains that run through interior Florida. And at that point it would probably make sense to extend Palmetto to JAX instead of terminating at SAV, and perhaps try to make a reasonably short layover between that and the FEC-based train. An FEC-based train should be able to connect JAX with West Palm (and therefore the entire West-Palm - MIA corridor by connecting with Silver Service or Tri-Rail) in significantly less time than it currently takes for the Star or Meteor to go Jax-MIA on the inland route. The question is whether to have the new service terminate at West Palm, which has no Amtrak servicing facilities or crewbase, or to have it continue to MIA. Servicing and crewbase argue for a MIA termination, while added congestion with existing rail service, freight, Tr-Rail commuter, and Amtrak Silver Service would argue for a West Palm termination, and possibly a Jupiter termination when Tri-Rail expansion to Jupiter is operational. On the other hand, Tri-Rail is really not set up to handle baggage, which would be necessary for the Amtrak pax.
As an aside, re Disney, Disney had wanted a rail system built from MCO (Orlando Int'l airport) through to Disney. That may or may not happen. It would be a boon to Disney and it's employees to have some sort of connection from Disney to the planned Commuter Rail, and I would expect that to eventually happen. As it stands, however, the commuter service will use the existing A-Line, which is east of I-4. If (and I expect they will ) they build a commuter station between Kissimmee and Orlando, Disney would undoubtedly run a bus connex to it's Park properties. Right now, four Amtrak Stations are part of the commuter rail plan - Deland, Winter Park, Orlando, and Kissimmee. The total build-out will have 17 station stops on the commuter system ('SunRail').
Here is a link to their current planning PDF:

As noted in that PDF, there is also a plan for Light Rail that would connect with the commuter system and go through the International Drive corridor south and west of Orlando and my guess is that it would eventually terminate at Disney which is on the far side of Int'l Drive from Orlando. The central point of this whole system apparently is planned to be the new Lynx (bus) multi-mode terminal recently built right along the rails through downtown Orlando with room for a large parking lot.
Anyway, if you go through that PDF, it will give you a good understanding of what is planned, rail-wise, along the S-Line and A-Line and through the Central Florida area, and any Amtrak route planning MUST take all of that into consideration. They are moving ahead with the commuter project - the land for the nearest commuter station to my home has already been purchased for that purpose, and the existing buildings razed and cleared. It will be a commuter rail station with a parking lot and a Lynx bus system connection run-through. Location is State Road 436 (Semoran Blvd) in Altamonte Springs, on the north side of S.R. 436, on the west side of the track.
