Formal accommodation refers to professionally managed, licensed establishments that provide lodging in exchange for payment, adhering to strict industry standards and government regulations. The most classic example is a full-service hotel, such as a Marriott or a Hilton. Unlike "informal" or peer-to-peer options (like a couch-surfing stay or a spare room in a private home), formal accommodation includes structured amenities such as a 24-hour reception desk, professional housekeeping, fire safety certifications, and standard liability insurance. Other examples include serviced apartments, boutique resorts, and licensed bed and breakfasts. In 2026, the distinction is important because formal accommodations are required to follow specific data privacy and health protocols that may not be present in more casual "homestay" environments. They offer a predictable, "contractual" level of service where the guest has clear legal protections and the establishment has a professional duty of care toward the traveler.
