The diving is wonderful - lots of critters and interesting formations. Additionally, there were terrific lectures about the area (history, geography, culture, etc.) and the opportunity to take a seminar in buoyancy control which was the best we have had. The head of the dive operation is a nurse but there is also a volunteer nurse who arrives daily during core hours - both were great additions as many people had ear problems and one had a lung issue while we were there. The no see ums were horrid - we jokingly referred to them as the Roatan measles. Remedies were available at the resort but the little bugs were still very annoying!
