My son and his girlfriend took lessons in the morning and went diving with one tank in the afternoon. They liked it so much that they took the second tank dive for an extra $25/pp. It's only in water up to 40' deep, but this was plenty for their first time. My daughter and I went along and snorkeled for the afternoon. It wasn't as densely populated with fish as Buck Island, but was very nice swiming in closer to the reef. We saw a big turtle and watched him for a while.
