I took this tour with my 10 year old son. I was pleasantly surprised. The "sea" part was particularly nice. Now, my expectations were were not very high so I may have been easier to please than if I was expecting something really awesome. Be aware that the descent into the viewing part of the boat is a bit steep and I would assume you have to be pretty steady on your feet to maneuver it. You are on the upper level of the boat (sea level) going out to where you see the fish and coming back. We saw a nice selection of fish on the excursion. A diver goes off the boat and feeds the fish to attract them to the boat. There are viewing windows in the bottom portion of the boat. The bottom portion of the boat is somewhat narrow. A bench pulls down and two people sit on each bench that extends the width of the boat. I would have liked a longer tour of the island of Curaco but what we saw was nice. I would definitely recommend it.
