We had a great time! The staff was friendly and accommodating. We had a week to get our Open Diver certification and had bad luck with visibility the first two days due to weather. They arranged a schedule just for us to complete the certification and we had a great time diving. We saw unique coral, exotic fish, sea turtles and more. The dive was a blast and the staff was fun and friendly. Our dive instructors were Denzel, Jack and Vlad each of them were knowledgeable and passionate about diving. I highly recommend using blue bubbles above any other dive shop in Saint Maarten.
