The post-war 1950s ushered in a building boom on a massive scale. By 1947, approximately 22,000 motor courts were in operation in the U.S. alone; a typical 50-room motel in that era cost $3000 per room in initial construction costs, compared to $12,000 per room for metropolitan city hotel construction. By 1950 there were 50,000 motels serving half of the 22 million U.S. vacationers; a year later motels surpassed hotels in consumer demand. The industry peaked in 1964 with 61,000 properties and fell to 16,000 properties by 2012.
