The amount of money that both Disney and Virgin can bring to bear will overcome any political barriers. Its called lining pockets. How do you think Disney got God like control over the Florida Project?Virgin wouldn’t be making money. None of those stations allow for dense real estate development by Virgin. Federal regulations also hinder the development of public transportation that focuses on tourist locations.
Stops along the route allow people to move about. That means more money for everyone. True Disney may not like having people use transit to visit other surrounding areas. But it will make money. If both companies are doing this then they are past the feasibility studies and they have been collaborating for years behind closed doors.
What we are seeing is years of work. The very tip of the iceberg. Nobody knows how deep this goes unless they are a part of it. Especially with UNI saying they highly support it.
The future of transportation is intermodal transport. I used to work for my state's department of transportation. And even I underestimated its importance.
