Leave that gigantic, four-wheeled suitcase for another time because you won't need to bring very much to the hotel. You'll likely be spending a lot of time lounging around in a robe and slippers, but these are generally provided by the resort. If you're planning to go for a splash around in the pool or participate in some relaxing aquatic activities, pack your swimming suit and a change of clothes. Casual, non-restrictive garments are the most comfortable. Considering using the fitness facilities? Bring workout gear and your favorite trainers. Oh, and don't forget to take your toiletries and other personal effects!
