My husband and I travel a lot and this experience is now on our list of most amazing experiences! The rays came within inches of us and it's so surreal! Our tour was at 6:30pm and I was worried that it might not be dark enough. But the sun was setting before 6pm so it was fun, plus the safety information and 20 minute boat ride pushed us past 7pm when we were in the water. Simon, Anthony and Chris took great care of us and we felt very safe and they shared lots of information about the rays. We got a wetsuit like jacket to put on that helped us float and they provided a pool noodle for our legs and feet. Our arms got a bit tired holding on for so long, but it was soooo worth it! We bought a cheap underwater Amazon camera and got some decent photos. We did get a little cold in the water so the warm shower on the boat after was very nice. Definitely bring a warm sweater as they suggest. I get sea sick so was a little concerned, but the water was calm and the boat ride was quick. I felt totally fine. My husband and I look forward to going back with our teens someday!
