From Statistics Explained
The number of bed places in a tourist accommodation establishment is determined by the number of persons who can stay overnight in the beds set up in the establishment, ignoring any extra beds that may be set up upon customer request.
The term bed place applies to a single bed; a double bed is counted as two bed places.
The unit serves to measure the capacity of any type of accommodation. A bed place is also a place on a pitch or on a mooring in a boat to accommodate one person. One pitch for camping / tent, caravan or similar shelter and one mooring for boat should be counted for 4 bed places if the actual number of bed places is not known.
