I'm looking forward to the train Brightline that will connect airport to Disney Springs in 2023. I love trains. It should run every half hour or more frequently, which isn't too bad for waiting. I don't mind hauling luggage because I have 2 teen sons who can do it. Once I get to DS, we can uber to the hotel.
I know that sounds complicated, but I suspect that's what Disney is expecting everybody to do in the future. I mean, why else have a train line from airport to WDW? It's to remove the DME. There can be no other reason.
Disney can resume the luggage hauling option so that people can take the train to DS without luggage, then jump on the DS resort bus. That way, each hotel's DS bus doubles as the airport bus. And those who want to haul luggage will have to take uber at DS. It's more clumsy than the DME, but not impossible.
I only wonder how close the train station will be to the bus station?
