My husband and I are coming the Key Largo Dec 13-16. When we vacation in the Caribbean we love to take a day sail where I can snorkel or dive and then we can sail around some and have drinks and a light meal or snacks provided. I'm open water diver certified and would love to go diving, but would have to have a buddy. My husband isn't a fan of getting into the water, just loves to sail. We don't like the crowds, we prefer a small company that takes 6 or so max. Any recommendations?
