When choosing what to take to your hotel, think comfort and functionality. Loungewear is a wise choice. Along with bathrobes, lots of hotels provide guests with toweling slippers. However, if you're planning on going to exercise classes, pack your favorite trainers. Want to hop in the steaming hot tub or hit the sauna? Swimwear is a must. While spending all day kicking back in next to nothing can be liberating, there may be a restaurant dress code if you're at a top-end resort. Bring something stylish to wear in your bag — just in case.
