We took the Nassau Harbor Cruise in July. It was ok but I do remember thinking it was rather pricey for what you got. It basically went up the harbor, just past Atlantis, stopped and fed the fish for a bit and cruised back. You did not go to the other side of Atlantis so you never really saw any of the nice beaches, etc. The captain will point out different homes belonging to famous people such as Oprah, etc. My kids liked feeding the fish and that was about it for them. If you do go, be sure to buy water from the locals before getting on the ship. Next time I would just stay on the ship with the kids and let them enjoy the pool and other amenities instead of trecking them around a bit in Nassau.
