Matt, the captain was very nice and kept our adventure close and personal. We saw a manta ray while heading out to the island to kayak and snorkel and he did a U-turn so we could see it. They only take a maximum of 14 people so it is kept warm friendly and personal. No over crowding here. Sam was our kayak guide. He is so laid back...perfect for our excursion. He was very knowledgeable about the habitat and the eco system. We saw two types of sharks, some barracuda's, some type of turtle and very cool birds (can't remember the types) Loved the clear kayak boats. When snorkeling, they take you where everyone is not so you can see your surroundings in the water and all the fish life. The bigger groups kick up a lot of sand so you don't see much of anything. My husband and I met some really nice people and enjoyed ourselves a lot.
