To be clear, my wife and I did not go into the water because we do not swim. So others may have a better experience. First stop for the star fish was good. Boat staff was great! Informative, helpful - nothing bad to say about them. We had already been there before - so nothing new for us. My beef - the bioluminescent bay is over rated. The pics make it look like you are walking on the beach near a glowing bay. Everything is glowing. Not the case. You drop into the water form the boat. In reality the glow is only from movement...paddling, kicking, etc. The pics are all enhanced. I think the experience would be fine if that is what is advertised....but it is advertised as way more than the reality.
