In Chino Hills, a hotel must provide a certain number of high-end conveniences to be designated 5 stars. These can include on-site gyms, saunas and spas, gourmet restaurants, premium bedding, luxury bathroom products and more. What also sets 5-star hotels apart is their guest-focused service. You can expect things like nightly turn-down services, concierge services and in-room massages. Some may also offer extra touches like welcome gifts.
