Leave that heavy suitcase for another time because you won't need to take much with you at all. You'll likely spend a fair amount of time dressed in a fluffy bathrobe and slippers, but these are often provided to guests by the resort. If you hope to go for a swim or involve yourself in some aquatic activities, pack your swimming suit and a spare set of clothes. Casual, loose-fitting garments are best. Thinking about taking an exercise class? Bring some workout attire and your favorite trainers. Oh, and remember to bring your toiletries and other personal effects!
