In Hill City, a hotel needs to provide a certain level of upscale conveniences to be designated 5 stars. These can include saunas and spas, on-site gyms, gourmet restaurants, premium bedding, complimentary luxury toiletries and more. What also sets 5-star hotels apart is their guest-focused service. You'll enjoy things like nightly turn-down services, in-room massages and concierge services. Some may even offer extra touches such as welcome gifts.
