Getting between Orlando and Miami is so much better now. I hated driving on the freeways down there, and now you can just lazily saunter onto a train, zone out with a movie or a book or whatever, get off at whatever station you want, call a ride and get to your hotel or wherever you're going.
Huge, huge fan of Brightline in Florida.
The only thing they could have done better is built a Port Canaveral station to facilitate getting to/from cruises from the Orlando airport. Very surprised they didn't do this!
