When choosing what things to take to your hotel, think comfort and functionality. Casual, loose-fitting clothing is a perfect choice. Along with robes, most hotels supply slippers. However, if you're planning on joining an exercise class, pack your favorite trainers or sports shoes. Hoping to soak your body in the hot tub or make use of the pool? A swimming suit is essential. While spending all day lounging around in practically nothing can feel very freeing, keep in mind dress codes may apply if you're at a high-quality resort. Bring something stylish to wear in your bag — just in case.
