In Marcus, a hotel needs to provide a specific amount of high-end conveniences to be designated 5 stars. These may include on-site gyms, spas and saunas, gourmet restaurants, complimentary luxury toiletries, premium bedding and more. What also sets 5-star hotels apart is their extraordinary standard of service. You can expect things like concierge services, nightly turn-down services and in-room massage. Some may even offer special touches such as welcome gifts.
