This was simply amazing. We took a cab from the port to Unexso. From there, we took a leisurely ride by boat to the Dolphin area. The dolphin trainers were fantastic. We pet dolphins and had a private dolphin show. The boat was late picking us up, so we had no time back at the port for shopping. I would have liked an hour buffer so we could have done some more shopping in Lucaya.
We didn't book an excursion in Nassau, but instead, walked around the main street. We stopped in for an ice cream break at a little shop off the main drag. We also went to the Pirate Museum, which was very enjoyable. The prices in the gift shop were competitive. I don't think Nassau is the place to get deals on jewelry, however. You may be better off on the cruise ship. We also stopped in for a snack in a restaurant and had conch fritters, grouper fries, and hummus. Very good, but slow service!
Very organized. The bus was comfortable. We had enough time in Magic Kingdom. The cost was only a slight premium over booking it ourselves.
