We have another Renaissance hotel that has a fascinating past and that's The Blackstone in Chicago. This hotel used to be known as the "Hotel of Presidents." Its Presidential Suite was occupied by many former U.S. Presidents such as Franklin Delano Roosevelt, Woodrow Wilson, Harry Truman, Dwight Eisenhower, John F. Kennedy and Jimmy Carter. The most famous room at this hotel is called the Smoke Filled Room, where a group of cigar-smoking Republicans helped secure Warren G. Harding his party's presidential nomination.
