I'm looking for an amazing dive vacation. We have a group of four... two will want to dive every day, including a night dive. Would love to see sharks / whale sharks. The other two will want to dive every other day but need a place where they would feel safe going off on their own for land fun. Any ideas? I've googled and googled. Came up with great dive locations, but am unsure about the safety of the area or the ease of getting to land-based attractions: Roatan - we went here on a cruise but the area did NOT seem safe. Traffic cops had MP5s and there was barbed wire surrounding the dive complex.
