it's tropical. so wear shorts, sundresses, and have a few bathing suits with you. the water will be able to walk in with no cold shock to your body, and it will be clear, so get an underwater disposable camera. you'll want to take pictures of the fishes and corals. You'll want to go on a catamaran trip. these are extra. about $150 pp extra is good to bring. food, liquor and cigarettes are included. There are lots of options for trips there too you'll want to do. Like taking a short bus ride to Ricks cafe to see the sunset or go diving off of a cliff. Be aware, alot of resorts butt up to each other, and alot of the resorts are clothing optional. and some excursions may stop at 'bakeries' that sell cookies and brownies made of pot. so if it's pricy, it's got pot in it. get there or bring from home sunscreen and aloe. the islanders cook it up right there for you. use SUNSCREEN, it's cooking time on your skin down there. have fun.
