The hotel boasted the first air-conditioned ballroom in America, and following the completion of the second tower, the hotel offered over 1,000 guest rooms. In 1908, the hotel's name was changed the Congress Plaza. Before long, the hotel had a second nickname, Home of the Presidents- a reference to visits by Grover Cleveland, William McKinley, Theodore Roosevelt, William Howard Taft, Woodrow Wilson, Warren G. Harding, Calvin Coolidge, and Franklin Roosevelt. Theodore Roosevelt's Progressive Party even gained its nickname Bull Moose because of a comment he made to reporters at the hotel.
The hotel is still a spot of elegance and luxury for travelers to the Windy City. Along with magnificent hotel rooms and suites, there are also two restaurants, a fitness center, and a barbershop. Every Halloween, the hotel hosts the Haunted Halloween Ball, a reference to the many ghost stories that revolve around the historic building.
