In Carrier, a hotel must provide a certain amount of top-notch amenities to earn a 5-star rating. These may include on-site gyms, saunas and spas, gourmet restaurants, premium bedding, luxury toiletries and more. What also sets 5-star hotels apart is their outstanding standard of service. You'll enjoy things like in-room massages, concierge services and nightly turn-down services. Some may also offer additional touches like a welcome gift.
