When deciding what to take to your hotel, think practicality and comfort. Casual, non-restrictive clothing is a wise choice. As well as bathrobes, lots of hotels supply slippers on arrival. However, if you're taking a fitness or yoga class, pack your favorite trainers or sports shoes. Want to hop in the steaming hot tub or make use of the pool? A swimming suit is a must. While spending all day in practically nothing can be blissfully fun, bear in mind dress codes may apply if you're at an upscale resort. Put something stylish to wear in your bag as well — just in case.
