In Phru Thai, a hotel must provide a specific level of upscale amenities to earn 5 stars. These can include saunas and spas, on-site gyms, gourmet restaurants, luxury bathroom products, premium bedding and more. What also sets 5-star hotels apart is their guest-centric service. You'll enjoy things like concierge services, in-room massages and nightly turn-down services. Some may even offer extra touches like welcome gifts.
