This is an amazing experience and worth doing at least once! The staff is extremely helpful, nice and considerate. They make you feel safe and comfortable throughout the process. I recommend getting the pictures and videos once done. A plus not knowing how to swim but can still do the excursion.

I would reccomend this tour. This was a really fun and accessible "adventure" experience. I was traveling with my family in a group of 5, with varying mobility. This experience was perfect because it provided a cool adventure-like activity for everyone while still allowing those in our group who couldn't take part in some of the more physical excursions we did earlier in the week to really enjoy themselves fully without the need for any modifications. The captain and each diver who accompanied us on the ship were all very personable and clearly experienced. The ship itself was clean, spacious and well stocked with waters and some snacks. We did get lucky and we only had about 12 people total on the boat, so it was virtually empty. While out on the bay, we were able to see a number of Turtles both under water and at the surface, as well as a huge variety of fish. There was also a fish identification guide aboard which was a nice small touch for our reference after we used the Scooters and free dived with the snorkle gear. No negatives at all. Book now!

Amazing experience! We saw a couple of turtles and a whole bunch of fish which come to you since you'll have a food pouch attached to your gear. They also have snorkeling gear when you're waiting for your turn or after your turn is up so you can still check out what's going on. You also don't need to know how to swim to do this activity although it knowing will help keep you from panicking when you have to go in the machine

They were very professional and well staffed. They helped with every aspect of using the scooters. Some people were kind of nervous before they got in the helmet and in the scooter and the tour employees took such good care to get them off and going. Absolutely fabulous!!
