I went with my dad and two brothers on a tour led by Carlos. We were part of a group of 12, which is on the large side. As a result it took us a bit longer to get out onto the water and to circle up at the places where we stopped to snorkel, but Carlos did a good job at managing a large group. He was patient but efficient, knowledgeable, and funny. We changed course at the beginning due to increased wind. Although I would have loved to paddle farther and spend more time on the water, I felt safe with Carlos' decision and we still had two snorkeling stops where we saw eels, beautiful fish, and lots of sea turtles! The underwater photography was an incredible added value, especially after Carlos gave us a group discount on the photo package.
