Amazing experience. So good I took the opportunity to stay on for the second tour which had space available. Just hanging out in the water with the manatees was incredible, as they were mostly completely unbothered by our presence and just kept on eating the sea weeds and grasses and one even went to sleep. Captain Gene was great and careful not to overcrowd, chase or bother any manatees that looked liked they would rather be left alone, and was rightly proud of their National Geographic Snorkeller status.
Planning to bring my wife along next time.
