Hotel and spas in O'Fallon
What should I bring to a spa hotel?The main objective is comfort and practicality while you're staying at a spa hotel, so loose-fitting clothing is generally the order of the day. While you'll likely spend a lot of time wearing a toweling robe and slippers, these are often issued to guests when they arrive. If you plan to use the resort's fitness facilities, pack your activewear and trainers. Hoping to reset and recharge in the pool or steam room? Don't forget to pack your swimming suit. In addition to toiletries and other essentials, bring extra clothing with you too. It's nice to have a clean, dry outfit to change into after a massage or body scrub.
