In Marcus, a hotel must offer a specific level of high-end amenities to be designated 5 stars. These can include gourmet restaurants, saunas and spas, on-site gyms, complimentary luxury toiletries, premium bedding and more. What also sets 5-star hotels apart is their extraordinary service. You can look forward to things like nightly turn-down services, concierge services and in-room massages. Some may even offer thoughtful touches such as a welcome gift.
