I stayed at the Hyatt Regency Phoenix for one night a few weeks ago for a convention. The location was very convenient since it was only a short taxi ride from the airport and right across the street form the convention center. The staff was friendly and the hotel was nice throughout. My room was clean, comfortable and quiet. I don't expect much more than that really. I didn't use any amenities other than the swimming pool and hot tub. That was one area of the hotel that could have been better. The pool area was very dated looking and showed signs of negligence and bad upkeep. This surprised me because the rest of the hotel was much nicer. Overall a fine experience with some room for improvements.
