NOT the Fairmont quality we've grown to know & love
I have never been so disappointed! After a 12 hour drive from the East Coast we arrived between 1:30 & 2:00 AM. We drove to the valet garage area (not the front door) as per signs but no one was available to park our car for the $58 fee. So we pulled into Aon's garage for slightly less and then began a trek around a block & through a maze until we were back on the street at the front entrance. 
Check in was up to standard & with an 8AM meeting, my husband requested and was granted a late check out to return and rest before our 8 hour drive to Toronto.
When we arrived to our large but slightly outdated (think 80s) room, there was a pubic hair by the toiletries, dust on the furniture and a missing remote control. A new remote was readily provided.
Unfortunately, the following morning hammering and drilling outside the window started early and continued rendering a late check out useless.
I called the front desk and explained that although we had received a very reasonable corporate rate, could they not have thought to put us on the quieter side of the hotel.
I went over numerous details with "Patrick" and was kindly told that the hotel was at full capacity, that guests had been notified of construction and then he asked if I would like a complimentary pot of coffee for my drive. What I really needed was 2-3 hours rest preferably with a complimentary massage in their spa! The Nespresso in the room worked just fine, thank you.
Anyway, this hotel's ONLY saving grace is its staff.
My husband only chose the Fairmont (out of 16 hotels) on MY request. This was HIS third stay but a frequent corporate visitor to Chicago, he had already chosen other hotels on more recent business trips. I live in Europe so this was meant to also be a few nice hours for us to be together. 
All I can say is that it wasn't the kind of Fairmont that I had grown up with. In fact, it might as well have been a 2 star motel.
With a son who spent his summer in Vancouver, (numerous Fairmonts), it pains me to even write this. 
There are too many healthy choices in Chicago to risk a repeat of this experience.
