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