This is a great experience for people with kids. The adults enjoyed the harbor tour of home on our way to the "submarine." Some reviews have talked about the lack of fish until they threw food off the ship at the reefs. We knew ahead of time that until you get to the reef, you will not see many fish. While we visited the three reefs, we saw lots of aquatic life including sea turtles, barracuda and sharks. The boys loved the experience. Both the harbor tour guide and the submarine guide were funny and entertaining. I am sure the third leg (part of the See and Sea Tour) would be excellent as well, but being that we already subjected the kids to one city tour, we opted to only do the short tour and head to the beach.
