Our group of 6 adults (5 experienced snorkeler and 1 newbie) did this 2 spot trip and 4 of us went on the night manta ray snorkel. They were both GREAT, perfect places to see turtles, fish, rays, eels, etc, fun smaller boat so we got to see lava caves and tubes up close, staff were knowledgeable and fun. We'd highly recommend using this company.
