Not sure why the big push for the Tampa Airport to Disney. Orlando has its own airport to handle Disney traffic.
This line doesn't include going to Tampa International. It just dumps passenger(s) in downtown Tampa.
Legoland won't benefit much from the line since the "station" in Polk County/Winter Haven area would be at least 30 minute bus ride/car rental ride from the station to Legoland.
Thus you have Tampa flight arrivals taking a bus or taxi from TIA to train station - to stop somewhere in Polk County/Lakeland/Winter Haven area which is a midpoint on the line - stop at Disney and stop at Orlando airport.
Rent a car and be to Disney in half the time for less money.
And who would pay to take the high speed rail 10 miles from Disney to Orlando MCO when Disney takes them there for free. And most of them have to turn in a rental car because they went to Universal, Sea World etc, as well as Disney and needed a car.
All the usual cast of Characters are crawling out of the woodwork and squealing like stuck pigs over the loss of this boondoggle, make work, create union jobs debacle cum blight cum black-hole-sucking-tax-dollars which makes the Big Dig look cost effective by comparison.
They even have TWO airports there for that kind of traffic!!!
