These are the largest hotels for groups in the largest city in the state of Illinois – which boasts an incredible 41,000 hotel rooms in total!

Our pick of Chicago’s hotels for groups, from the historic opulence of Palmer House, a Hilton Hotel, to the gargantuan Hyatt Regency Chicago, which boasts 2,019 rooms.

  1. Hyatt Regency Chicago

    Officially the largest hotel in Chicago, and one of the largest hotels for groups in the world, the Hyatt Regency Chicago has a staggering 2,019 rooms; among them 93 suites and parlours. The hotel is as centrally-located as they come; many of the city’s star attractions are a stone’s throw away. For example, The Art Institute of Chicago, Navy Pier, the Magnificent Mile and Grant and Millennium Park are all just a short walk away, as well as the shores of the epic Lake Michigan.

  2. Palmer House, A Hilton Hotel

    The second largest hotel in the Windy City is Palmer House, a Hilton Hotel, which lays claim to 1,641 rooms. It’s perhaps most famous for its grand, opulent lobby, complete with Tiffany chandeliers. As a member of the Historic Hotels of America, it is recognised by the National Trust for Historic Preservation as one of the finest hotels in the US. Sample seasonal American cuisine at the hotel’s own Lockwood Restaurant, or grab some comfort food at Potter’s Chicago Burger Bar.

  3. Hilton Chicago

    The third largest hotel in Chicago, and one of its most historic hotels for groups, the 1,544-room Hilton Chicago opened in 1927. Among these are 13 recently-renovated hospitality suites, ranging from 800 to 1,400 square feet. All boast views of Lake Michigan and have a living room area. There are three dining options at the Hilton Chicago: the 720 South Grill, serving local Midwest fare, the Herb N’ Kitchen culinary market, and Kitty O’Sheas Irish pub.

  4. Hyatt Regency McCormick Place

    The fourth-largest of our round up of Chicago hotels for groups is the Hyatt Regency McCormick Place, with 1,258 rooms and 51 suites; executive suites boast incredible views of Chicago’s iconic, skyscraper-studded skyline. Be sure to try out the heated indoor pool and the fitness centre, which is open 24/7. Restaurant-wise, you could opt for Southeast Asian tastes of Sixes & Eights, or the international cuisine at Third Star.
