Show management's travel partner, onPeak, books the "Show Hotels" at the show's negotiated rates. Booking one gets you the show's free shuttle buses, which run between McCormick Place and every Show Hotel (or a point nearby) on show days. The shuttle schedule is posted in the winter.

McCormick Place is at 2301 S Martin Luther King Dr, Chicago. If you are staying at a Show Hotel, the free shuttle is the simplest way in. For accessibility services, McCormick Place publishes its own details for wheelchair users and other visitors.
