In reality we often find more than one accommodation type in an establishment. Possible solutions to the problem are to:
split up the establishment into two (or more) establishments. This is the best solution if the establishment is able (and willing) to do so;
disregard the second accommodation type if its capacity is less than the specified minimum threshold of the country;
classify according to the main type. The main type may be determined by capacity (most often) or by use of capacity (or other criterion).
