One item of note, I think at all three ports the ship was ~60 minutes late or more disembarking, so they adjusted the return time at one port and obviously shifted all the Disney excursions to match, but if you're doing things on your own like we were that's something to take into consideration, the possibility of it taking a little longer than average since they are infrequent ports for Disney. We rented cars (the electric GEM vehicles at Bar Harbor,
Avis at the other two within .5 miles of the ship) and they didn't care when we showed up so we had no issues tthe
