Q: My stay at the Fairmont Chicago Millennium Park Hotel was by far the worst hotel stay I ever had. I would not recommend this hotel to anyone. They promised I would be able to relax in the spa area and it was dirty and not relaxing at all. When I got to my room I ordered room service and it took them 45 minutes to bring what I ordered. I am highly dissatisfied.

A:
negative
