When deciding what to take to your hotel, think practicality and comfort. Casual, loose-fitting apparel is an ideal choice. Along with bathrobes, most hotels provide guests with slippers. However, if you're planning on going to exercise classes, pack your comfy trainers. Hoping to hop in the hot tub or enjoy a splash about in the pool? A bathing suit is a must. While spending all day relaxing in next to nothing can feel very freeing, remember that there may be a dress code for the restaurant if you're at a first-class resort. Bring a smart outfit in your bag — just in case.
