A fine hotel in a good location
I stayed at the Hilton Garden Inn Dallas/Market Center on Labor Day weekend. I was in Dallas for an Ambit National Meeting which was held at the Anatole (next door). The Anatole was booked so we selected the Garden Inn because we could walk through the parking lot to our meeting. We found the lobby to be clean and the check-in was fast. Our first room smelled like smoke BADLY(it is a non-smoking hotel) -- why on earth do people smoke in non-smoking rooms?..., so I called down to the lobby and they switched us to another room. The new room was right next to the laundry room, and I was worried that the vibration would be noisy. That was not the case, and we found that the proximity to the laundry room was nice because our room smelled like laundry soap freshness! 
There was a letter slipped under our door that there was a scam going on throughout the hotel where somone will call you and mention that your credit card had not been properly scanned upon your check-in. This paper warned us not to give our credit card to anyone who calls your room. Our phone did ring one night at 3 am, but I did not answer it, and then unplugged the phone from the wall. So perhaps that might have been someone trying to scam me!
Overall, the hotel was a fine value for the money. We did not eat there. The breakfast was not included with our stay (costing $10.99) so we opted to skip breakfast. I would stay at this hotel again if I wanted to be right off the interstate.
