Leave that huge, expandable suitcase at home because you won't need to bring very much to the hotel. You'll likely be spending a lot of time lounging about in a robe and slippers, but typically these are provided to guests by the resort. If you're hoping to go for a swim or get involved in some relaxing aquatic activities, pack your swimming suit and another set of clothes. Casual, non-restrictive garments are the most comfortable. Contemplating using the fitness facilities? Bring some workout attire and your trusty trainers. Oh, and don't forget to bring your toiletries and other personal effects!
