I just stayed at the Holiday Inn in Chicago last week. There were many things we did NOT like! It is VERY NOISY! You can hear the traffic and noise from outside as well as people in the next rooms. You can hear people partying in the hallways all night. If you want a good nights sleep this is NOT the hotel for you. The tiny pillow were hard as rocks and the bed was uncomfortable. We were tossing & turning all night. The food was horrible and they charged outrageously high amounts of money for it. The room key did NOT work! The room was freezing. Overall, I would not recommend it.
Cons: noisy, uncomfortable, loud
