Motel Inn in San Luis Obispo, California, is the world's first motel. It was built in 1925 by LA architect Arthur Heineman, who coined the term motel meaning "motor hotel." Motel Inn was originally called the Milestone Mo-Tel. Back then, one night stay was $1.25. Heineman couldn't afford the trademark registration fee,
so his competitors were able to use the word "motel." The motel is still in operation today.
