Using TGV as a base, I found it would be cheaper and faster for a family of four to just take a taxi.
This idea of a shuttle between the airport and Disney is just silly. High speed rail is about distance. How is Disney going to coordinate all of these families being stuck at the airport for hours waiting for the next train?
THIS is a great question!
I think they will run an "out and back" shuttle in the times the HSR is not running. They have said the HSR will run hourly so let's use the top of the hour as an example. The HSR will leave MCO at the top of the hour and bypass WDW and go directly to Lakeland and then Tampa Airport. After the Tampa HSR leaves MCO a shuttle could arrive at the quarter hour and depart for the Convention Center/WDW. Another shuttle at the half hour and another at the 45 minute mark. This way the longest someone would have to wait is less than 30 minutes for a shuttle.
As for the operating expenses many are concerned about, there is enough of a captive audience (tourists arriving for Uni and WDW) that the operating expenses should be covered. I really think this will be like popular Amtrak lines and will make a profit. If so, the state could consider selling or leasing the line. If it is a big loser, at least we won't start wasting money trying to build a nationwide network of HSR.
I also believe there are places where HSR can work. This system, and it is a complete system, can prove that and if it does private industry can then get involved.
