The number one goal is being comfortable and relaxed when you're at a spa hotel, so loose, casual clothing is recommended. While it's likely you'll spend much of your time wearing little more than a fluffy robe, these are often supplied to guests on arrival. If you plan to use the resort's exercise and fitness facilities, pack your workout gear and trainers. Hoping to kick back and relax in the pool or sauna? Don't forget to throw a swimsuit in your bag. Along with toiletries and other personal belongings, bring some spare clothes with you too. It's always good to have something dry and clean to change into after an oil massage.
