In Arctic National Wildlife Refuge, a hotel must provide a specific amount of upscale conveniences to be designated 5 stars. These may include saunas and spas, on-site gyms, gourmet restaurants, luxury toiletries, premium bedding and more. What also sets 5-star hotels apart is their guest-centric standard of service. You can expect things like in-room massages, nightly turn-down services and concierge services. Some may also offer extra touches such as welcome gifts.
