I also suggest taking the train. It’s really easy, the station is right there, and it’s cheap. As for breakfast, consider Cabanas. We had early seating, so breakfast at 7:15, and it was very chaotic, definitely the worst dining service of our trip. After breakfast, we were lucky to find a couple of chairs in the Promenade lounge to wait for our group to be called. There were crowds of people waiting everywhere, but once we got off the ship, everything was pretty quick.
