My husband and I recently stayed at the Fairmont Chicago Millennium Park. What I expected to be a very pleasant experience, turned out to be a stressful visit. We specifically reserved a non-smoking king room and paid the price for that reservation. Upon arrival, the hotel did not have any non-smoking rooms available and the representative at the check in desk was not helpful. As we had no other options, we accepted a smoking room with two queen beds. I can live with the bed situation but I truly feel that having to accept a room infused with cigarette smoke is completely wrong! There wasn't an area in the room where I did not feel nauseous from the stale smell and I cannot help but think that this smell followed me around all day after check out. To add insult to injury, the hotel staff was not sympathetic to our situation -- something I think they should be specifically trained to do -- and did not offer any compensation, partial refund or related "perk" to make up for our great inconvenience. Two staff members actually acted as if I was the inconvenience in asking them if there was anything they could do! Although we paid for the breakfast package, we were eager to leave immediately in the morning and dined elsewhere at our additional expense. Pardon the pun, but we just could not sit there and dine in the morning with such a bad taste in our mouth from the hotel's lack of customer service! I am hoping the corporate office responds to our complaints but, thus far, we have received no satisfaction. Needless to say, we will not be visiting this property again! In fact, we are no longer going to patronize this brand of hotels.

When I planned my summer vacation, I was wanting to travel somewhere new. Chicago was on my mind because of the fast city life. I got in a flight to Chicago and arrived at the Hard Rock Hotel. It was grand and I spent a total of 4 days and nights there. The luxury was exotic and the location was right around the corner from most shopping and dining venues. The room service had me drooling because the food was so delicious, I could hardly picture not feeling satisfied. I met up with a few of my friends and they offered me a tour around town. I enjoyed the stay there and will come back sooner than later.
