we are starting to plan a diving/snorkeling vacation for next summer. Originally we were planning to go to Cozumel, but were told there are better reefs in Central America. There will be 6 adults - 1 experienced diver, 2 who want to get certified and 3 snorkelers. We want to rent a house or condo ($300 ish per night) on a beach. What are some locations we should consider?
