If you need a bed for the night, Hilton has a few hundred thousand of them. The company is one of the world's largest hoteliers with a lodging empire that includes more than 4,600 hotels and resorts in about 100 countries operating under such names as Doubletree, Embassy Suites, and Hampton Inn, as well as its flagship Hilton brand. Many of its hotels serve the mid-market segment, though its Hilton and Conrad hotels offer full-service, upscale lodging. In addition, its Homewood Suites chain offers extended-stay services. The company franchises many of its hotels; it owns the Waldorf-Astoria brand and the New York Hilton. Hilton became a public company again in 2013.
