We booked our hotel stay thru Yahoo and requested a room for 4 with 2 beds. When we got to the hotel, not only did they not have a room for us (we pre-paid!), but they said they could not guarantee what we had requested online, they could only give us what was available. The hotel staff was rude and condescending and only after I got upset did they finally tell me they did have a room for us. If you book online - beware! You may not get what you paid for. They did not stand by their promise they advertise in each room.

Hyatt Regency Chicago seemed like a nice place to stay, but we didn't like it very much. The renovations were cheap and poorly done (our bathroom faucet was leaky and the carpet had bumps in it.) The staff was RUDE! I was trying to find a good cab service, and the guy behind the front desk made me wait for 20 minutes while he was finishing a phone call! Couldn't he have at least called someone else to help me? The "Babies Travel Lite" gave us the wrong sized diapers, so we had to go find some anyway, and with the hotel being located in the heart of the city that meant we found some unsavory characters along the way.

After a my stay at the Millennium Knickerbocker Hotel Chicago I contemplated the the poor quality of my experienc there and felt the need to document it. While the amenities were plush, the service of the staff was lacking. Upon check in, my reservation was "lost" and it took over 30 minutes for the manager to make arraingments for my stay. There was no offer to upgrade me or comp me in any way. Room service did a poor job in cleaning my room and left wet towles in the bath room. A used coffee filter was left in the coffee pot for me to clean out. I am not sure my sheets were changed out. When I checked out, the bell hop dropped my laptop and destroyed my hard drive leaving me to scramble to recover the report I spent days creating. Overall my negative experience has left me wondering if they train thier staff on the proper way to attend to their customers. I will be relunctant to stay with them again until I am assured they have focused on trainging their staff better.
