Where to get the Royal Caribbean bus from DC?
There’s a bus terminal that seems to be used for a limited number of Grayhound buses and charter buses from Union Station itself. It’s on the way to the parking garage. It may be there. The exit from the main area with the train terminals is close the center and on the second level. I believe that is what is meant by Union Station when talking about non-local buses. It may also be out front near the Taxi stand, but I’ve never see a bus there.
