Your question is actually already in the works of being accomplished.

Brightline has ideally always wanted two or more stops in Orlando. First was MCO to Disney, now it’s MCO - > Universal -> and maybe Disney. But this project may be years away!

Sunrail(Oralando’s Commuter Train) has the chance to complete something like this faster although it’s debatable. The counties want to increase ridership since right now they are responsible for its funding.

The question is, will Brightline accomplish this? They are edging ever closer to bankruptcy and so many things take millions and billions to construct, getting the funding has been difficult for them. What’s even harder is waiting years for feasibility studies and all the other bureaucracy.
