Problem:During my recent stay at the Hyatt Regency Chicago, I was severely disappointed in the quality of the facility and its staff. To start off, the rooms did not provide an adequate sound barrier between rooms. Hoping to spend a quiet evening after a long day of business meetings, I had hoped to spend a quiet night in. My neighbors, however, watching what I can only imagine was a Real House Wives of New Jersey marathon on full volume, destroyed my chance for peaceful ambiance. When I asked the concierge to address the issue, he seemed more concerned about his texting than doing his job. As I visited the gym, I found their "state-of-the-art" StayFitTM gym consisted in nothing more than a couple of treadmills, weights and yoga mats. The water in the cooler was quite warm, and the workout towels were stained and tattered. Finally, all the hypo-allergenic features touted on their website were rendered null by the presence of dust balls under the beds.

Solution:
negative
