When choosing what items to take to your hotel, think comfort and practicality. Loungewear is the perfect spa attire. As well as bathrobes, a lot of hotels supply toweling slippers. However, if you're joining an exercise class, pack your favorite trainers or sports shoes. Hoping to soak your body in the steaming hot tub or dive into the pool? Swimwear is a must. While spending all day lounging around in next to nothing can be liberating, dress codes may apply if you're at a top-end resort. Put a nice outfit in your bag as well — just in case.
