It was a super awesome experience. We swan with the manatees. Right above them, beside them, with them. Lots of rules to follow in order to respect the wildlife but we were bombarded with so much that you almost didn't know once you were next these gentle giants you didn't know how to handle them. You technically cant touch them. The guys / instructors Tom and Jerry were awesome. Made the trip relatively fun and very interactive. My last key note is they did a phenomal job of advertising. My main reason for the 4 vs 5 is the fact that we were definitely near blue clear water. I was almost hesitant to get in because it looked swampy but the experience was nice.
