An extensive arc Campaigns to prevent reef damage and save endangered species discourage or prohibit collecting specimens, but the thrill of underwater exploration is nonetheless present -- and discovering buried "treasure" is always a possibility. Dive vacation values can be found at some all-inclusive resorts and in standard hotel packages priced to include dives and equipment. Resorts large and small provide (or will arrange) beginning scuba instruction -- a basic "resort course" -- and, following it, an intensified "Y" course, combining swimming pool and open water instruction, for PADI (Professional Association of Dive Instructors) certification. Resorts and dive shops offer a menu of regularly scheduled day and night dive excursions with escort/instructors who know the local waters and are thoroughly schooled in emergency procedures.
