The Hyatt Regency Dallas is a 28-story, 1,120-room hotel in Dallas, Texas' Reunion district. The building is connected to Union Station and Reunion Tower, which is the city's landmark observation tower. The Y-shaped building has an atrium on the south side. In 1998, the hotel added a low-rise ballroom with an area of 32,000 square feet (the equivalent of 3,000 square meters). The Hyatt Regency Dallas recently completed a $50-million renovation that features newly redone guestrooms, bathrooms and corridors.
