Visiting Dallas for 3 days. Never been there before. Need info on sites to see and area to stay. Is Dallas a spread out city that requires a car rental? Or could you stay downtown and walk to the main sites. How far is DFW from downtown, or the main area you'd recommend to stay in? What's the weather like in late October? Any must try restaurants or foods (ie BBQ?). Doesn't have to be fine dining either. Is Dallas an easy town to get around in, with or without a rental car? How's the bus or subway system? Are all the main sites easy to get to without a rental? I haven't checked the Cowboys schedule yet but are Tix already sold out for home games this season? Any other sports in the area come late October? Thanks in advance!
