First and foremost, check if your hotel has any sort of dress code. You'll likely be given slippers and a robe, but not always. Underneath, you should aim to be as comfortable as possible; track pants, yoga bottoms, loose-fitting T-shirts and sweatshirts are often suggested attire. Trainers and sports shoes are normally allowed, but limited to dry areas. It's also a great idea to bring another swimsuit and a change of clothes with you.
