From Statistics Explained
The number of bed places in an establishment or dwelling is determined by the number of people who can stay overnight in beds set up in that establishment, ignoring any extra beds that may be set up following a specific customer request. The term ‘bed place’ applies to a single bed. A double bed is counted as two bed places. This unit serves to measure the capacity of any type of accommodation. A bed place is also defined to cover a pitch or, in a boat, a mooring that can accommodate one person. A pitch for a tent (if counted), caravan, mobile home and similar shelter, or a boat on a mooring, is usually counted as four bed places if the actual number is not known.
