I will never stay at a Hyatt especially in Dallas again. I had the worst experience ever. My daughter had a dance convention there so we arrived fairly late. We were unable to be by the group with were with unless we wanted to pay another fee. Once we arrived upstairs into our room, it smelled. Of course we were tired so just went to bed. The next morning we realized that the mirror by the tv was never cleaned (looked like someone spit something on it) and the bed by the window had mold or some type of black stuff on the top comforter. Once it was addressed it took the hotel three times to finally come up and change out the comforter and at 11:30PM finally cleaned the mirror. To top it all off the next morning as my oldest daughter was getting dressed, we heard sirens, she looked out the window and there was a dead body above the awning of the entrance. This is defiantly not a place to stay at the extreme high rates they charge. I have never stayed at hotel with such poor customer service and very uncleanliness.
