Conditioner for your hair (its not supplied). Bug spray (esp for the evenings down by the beach). I wish I'd brought more cover-ups, but I bought a sarong in the gift shop and it did pretty well all week. I agree w/ bringing a watch. It's nice to have on the beach. Bring a book for the rainy periods maybe. I brought 2 waterproof cameras and ended up buying a 3rd in the gift shop. At home they were $9, in the gift shop $22 - so you may want to bring 1 more than you think you need.
