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