Avoid the Hyatt Regency
I had not realised how down market the Hyatt Regency chain has now become – arriving late in Chicago from overseas with a Gold Hyatt Passport card and a guaranteed booking, they gave me a room which the “cleaners” had left in a disgusting state. When I refused the room the only offer was one where the bath room lights did not work. This hotel is large and impersonable, the rooms are basic and tired with a musty odour, better to eat at the many places close to the hotel or across the river.
Chicago hotels are generally of variable quality and conferences can result in large variation in room rates. Sofitel is a better than average business hotel, occasionally the Trump may have decent rates, but avoid the Hyatt Regency.
