We spoke with over 30 hotels and the ASCO conference has blocked off every hotel in Chicago until April 24th. We are hoping rooms will become available after that date, but in the meantime we have negotiated rates at https://www.HotelPlanner.com/EventPage5184863

Any reasonably priced hotel (under $200) is going to be near O’Hare Airport, which is about a 20-25 minute Uber ride from the event. We suggest a hotel with free cancellation, so if the rooms open at a hotel nearby after 4/25 you would have the option of rebooking.
