Anxiety turned into memories!! - What an experience!! We met at a Hilton hotel and was placed in a small group of 6 with 2 instructors. I was getting really anxious and the instructor kept checking on me. Once you put the helmet on and go under water, you feel the helmet get lighter. You only go 15 feet below to see the fish and the tour guides constantly check to make sure you’re ok. I LOVE the fact they had an underwater go pro to take videos and pictures. Would definitely come again. Oh! And once you’re day you can hangout for a few hours at the Hilton’s pretty pool/ beach area. Definitely coming back!!

Great experience with my family - Takes a little getting use to being inside the helmet, but after a couple minutes your body and breathing adjust.
