To combat the humidity and keep you comfortable pack several cotton t-shirts, dresses and shorts. A pair of hiking sandals, to explore the island via the many scenic trails. Or a good pair of sneakers will do the job as well. Open-toed footwear will be more comfortable; you can easily buy a pair once there as well. Take a few dressy clothes, in case you intend on visiting an upscale bar, restaurant or night club. Swimwear, of course, will be essential as the beaches are the main draw for the island. Pack at least two swimsuits so you an extra one waiting until the other one dries off. A big floppy hat and sunglasses are important accessories to keep the bright glare off your eyes. Bring your favourite pair of sunglasses from home, as most sold on the streets are of cheap quality and break easily.
