Newly renovated. Best airport hotel.
On a quick business trip I stayed one night at the Grand Hyatt at the Dallas airport. The rooms were huge, high end and very clean. Bed was awesome. The view from my room was awful because all I could see was the top of the terminial roof, but I just kept the sheers drawn. The room service was fast and food was much better than expected. Be aware, there is no buffet for a quick breakfast stop, so the service was a bit slower than I had hoped. But it was worth it because the food was fantastic. I would stay again.
