Hilton Chicago O'Hare Airport
The restaurant closed at 9 pm and I inquired about ordering at 9pm. I’m so glad they accommodated me very last minute! Room was great, the TV needed to be reset, an IT engineer came up promptly to fix! Definitely will stay again!

Crowne Plaza Chicago Ohare Hotel & Conf Ctr by IHG
Overall the room was fine but there were insufficient blankets on the bed! Upped the room temp to 72 (and I'm used to 68 at home) and still used a bath towel as an added blanket!
