The main objective is being comfy and relaxed when you're at a spa hotel, so loose, non-restrictive clothing is generally the order of the day. While you'll probably spend a lot of time wearing slippers and a bathrobe, these are usually waiting for guests on arrival. If you'd like to take advantage of the resort's exercise facilities, pack your workout gear and trainers. Hoping to release some tension in the pool or hot tub? Remember to throw a swimsuit in your bag. In addition to toiletries and other essential items, bring some spare clothes too. It's always nice to have something clean and fresh to change into after a massage or body treatment.
