Myself, my wife, and two teenage boys took this excursion to swim with the manatees. We only swam with one, a juvenile, but we were off away from all the other traffic on the river. It made for a great experience. Dakota is very helpful, knowledgeable and personable, making him an excellent tour guide. He also snapped some great photos during the excursion, making for a wonderful souvenir. Captain Jim is also fun to be around and did an excellent job getting us to the manatee and back through the busy river. The equipment we used was in great shape. I highly recommend the full face masks. I've snorkled before with the standard mask and snorkel, but I think the full mask provides a better experience.
