Caesars Entertainment Corporation (formerly Harrah's Entertainment) likes to spread its bets. The firm owns and/or operates more than 50 casinos (under such names as Harrah's, Horseshoe, and Rio) in seven countries. Altogether its facilities -- including hotels, dockside and riverboat casinos, and Native American gaming establishments -- boast more than 3 million sq. ft. of casino space and some 42,000 hotel rooms. Among its many locations on the Vegas Strip are Caesars Palace, Paris Las Vegas, and Planet Hollywood. It is owned by Hamlet Holdings, an affiliate of Apollo Advisors and TPG Capital. In 2011 the company filed to go public; the proposed deal comes about a year after it cancelled a previous IPO.
