In Nevada, a hotel must offer a specific level of upscale conveniences to earn a 5-star rating. These can include gourmet restaurants, on-site gyms, saunas and spas, complimentary luxury toiletries, premium bedding and more. What also sets 5-star hotels apart is their superior service. You can expect things like nightly turn-down services, in-room massages and concierge services. Some may also offer thoughtful touches like a welcome gift.
