The term "double occupancy" refers to a type of accommodation where two people share one room. This typically means that there are two separate beds, or perhaps a double bed, within the same space. The phrase is often used in the context of hotels, motels, hostels and other types of lodging establishments where multiple rooms may be available for rent to guests. In some cases, "double occupancy" can also refer to two people sharing a vehicle or aircraft seat during travel.
