Brightline offers free first/last mile transportation within 5-miles of their station. I assume they'll do the same up here, which gives you direct trips from the station to any Disney hotel. In effect, it'll be just as easy as using Disney's buses.OK, interesting detail here: Disney Springs no longer a stop on Brightline’s Miami to Tampa route
“In addition to the airport, one new station will be located at the Orange County Convention Center and an alternative station will be placed near the original Disney Springs site, albeit not on land owned by Disney. Taken together, the three integrated stations provide access to the largest economic and employment centers in Central Florida and offer the best opportunity for the success of Brightline and SunRail,” Ben Porritt, Brightline SVP of corporate affairs, said in a statement.
So coming to just outside of Disney. So get there then take Uber/Lyft/Taxi (or maybe Mini Van) to your Disney destination. I'm guessing the thought on Disney's part is to make it harder for their guests to go to Universal by creating an extra step.
