There are lots of cruises. There are party boats with a Carribean theme, a pirate theme, and this time, we opted for a lobster/steak jazz sunset cruise. We booked through our hotel, and it was about $50 per person. It was romantic, with a funny, lively crew, and they fed us very well. You had a choice of either steak or lobster.
After enjoying the sunset with the saxophone player playing in the background, we continued to enjoy the cruise by starlight. Very nice! We saw some families, but it was more geared toward a romantic good time.
