Great place to stay
My wife and I stayed at the Congress Plaza Hotel for four days and nights. Great location to all local attractions the taste of Chicago was going on at the same time was a great experience. Staff was very polite and helpful. After a long day of site seeing you could see the firework show from our room from the Navy Pier. To experience this ask for a lake view room it is breath taking.
The one thing I would ask is that the windows were cleaned on the outside and that snack vending machine were avaialbe plenty of drink vending machines and that the towel rack was closer to the sink overall I would stay there again.
