As you'll likely be spending a decent amount of your time in a plush bathrobe and slippers, you won't need to bring too many belongings. Besides comfortable clothes to put on after your spa treatments, personal items such as underwear and deodorant should be right at the top of your packing list. Of course, if you intend to make use of the resort's swimming pool or engage in exercise sessions, squeeze a bathing suit and some workout clothes into your bag as well. Finally, leave your electronic devices behind and bring something light to read instead. It is, after all, an escape from the real world.
