Input: The Hyatt Regency Chicago Hotel offered PDA or kiosk check-in which was great. They also offer hypo-allergenic rooms with air purification systems which gave us a much more delightful stay. We enjoyed the 24/7 stay fit gym, iHome stereo with iPod docking station, flat screen tv with video on demand and Wi-Fi. Concierge staff was very helpful with assisting us with finding excellent award winning dining and popular attractions in the area. We enjoyed our stay and will definetly return to this hotel in the future for family and business trips.

Output:
positive
