In Rong Kho, a hotel must offer a certain amount of upscale amenities to be designated 5 stars. These can include on-site gyms, saunas and spas, gourmet restaurants, luxury bathroom products, premium bedding and more. What also sets 5-star hotels apart is their guest-focused service. You'll enjoy things like concierge services, in-room massages and nightly turn-down services. Some may even offer additional touches like welcome gifts.
