We took a taxi to the Port at 1:30 and were in our cabin within about 15 minutes.
We had a mini-suite on Dolphin, which was very nice with plenty of room for all three of us. The balcony has little privacy, because the other decks can see onto the Dolphin deck, but I think that may be the price for having a mini-suite room.
The Kid zone was well staffed and the program seemed to have a lot of activities for those days at sea. My son was excited about attending the program until toward the end of the trip and by then he was burnt out on going off to camp (he comes by this honestly).
The food in the dining rooms was generally good with some meals very good. The service was excellent. We had dinner in the Crown Grill as well and thought that meal well worth the extra price. The Horizon buffet and Caribe buffet were at best fair and I would suggest either the pizza at the pool or the International cafe instead of the buffets. The pastries at the International cafe were exceptional in the morning and that was where we had breakfast most days.
We went on two excursions, Ocho Rios and Grand Cayman. At Cozumel, we took a taxi into town to do some shopping, which was fine.
As to the motion sickness, it was fine except for going through the Straits of Florida on both sides of the trip. I had a patch on for the first half of the trip and used children's bonine for the return trip.
