Microstays refers to occupying residency in a hotel room for less than a day. Although a relatively new term in the Western travel industry, it emerged as a trend in the World Travel Market Global Trends Report 2013. Day-use rooms became more popular in Europe during a time of recession when fewer people were travelling and hotels needed other sources of income. Microstays provide a way for hoteliers to boost revenues, as they can increase room inventories by selling the same room twice in a day.
