Where we(EGL) and AA stay, at the Admiral in Arlington TX isn't the nicest area either. I wouldn't go out at night. There have been vehicles stolen in the parking, somebody held up at gun point across the road at the gas station/subway, and there is a reason that there is a police presence there in the wee hours of the morning. I have personally been chased back across the road to the hotel from a friendly visit, during the day, to the subway. Guess it could be worse though.
