Bill Marriott has revolutionized the hotel business over the past four decades. As CEO of the company that bears his family's name, Marriott led the industry in opening hotels next door to highway exits and suburban office parks. He was also a pioneer in catering to niche markets. In 1983, he launched Courtyard, a chain for cost-conscious business travelers. Today, Marriott has 18 brands, including Fairfield Inn for budget travelers and Ritz-Carlton for the luxury set.
