[Q]: My stay at the Hyatt Regency was an experience that I'll never ever forget - not in a good way. Check-in was actually pretty easy and the clerk was pleasant. I went up to my room and looked around, all seemed ok at first. I was bushed so I flopped on the bed... ohhhhh noooooo! The bed was as hard as a military bunk from my Army days. But I was so tired that I just passed out. Of course I woke up with a back ache...great. I figured a hot soak in the tub would help my back so I plugged the tub, turned the hot water on full force, and poured in some shower gel. I put my foot in expecting some real heat - the water was barely lukewarm. I called the front desk but they were no help, the clerk just apologized. Frustrated at this point, I turned on the tv and switched on the air. I put my hand over the vent to see how cold the air was and I saw something slimy inside of the vent. It looked like a wet gray chunk of goop or something. I couldn't take anymore of this. I went down to the front desk and complained to the clerk. It seemed as though the guy was on something - he kept smiling as he apologized, no empathy as if he's used to hearing about the goop in the ac. He offered me a free night but there is no way that I'd stay at this place again - ever.

[A]: negative

[Q]: The Omni Chicago is hands down, the best hotel in my opinion in the chicago area. I am a neat freak but here you need not worry about cleanliness as they are the best at keeping the rooms tidy. Our check in was easy and fast and the staff at the hotel was very courteous and friendly. I forgot my hair dryer but thankfully, one of the many perks at this hotel, they provide one for you in your room! That's a small benefit compared to the lucious pool and dreamy massages they offer! I have never had a massage like that before! My favortie thing about the Omni is the high speed wireless internet that is available to all guests. I am able to do my work online in all areas of the hotel which saved me a lot of time as I was not at my office but still had a lot of work to get done. I also LOVED the TV they provide in the room. A big plasma with a beautiful, crisp picture! I don't even have that at home! Needless to say, I spent almost all night lounging in the comfortable bed watching movies only to fall asleep and wake up to the newspaper delivered to my hotel door in the morning! I will be coming back to the Omni on my next trip to Chicago. That's a promise.

[A]: positive

[Q]: This hotel was very poor with customer service. They were so worried about keeping everything up to date and perfect looking in the hotel they rarely worried about their customers, and their guests. I had to ask for my room to be serviced for cleaning, and it took a long time to get a response. Very disappointed.
