one other possibility is to stay in DC. It's an easy cab ride from the dupont circle area, for example to DCA. Maybe 15 minutes max. Advantage is much more interesting environment. No offense, NoVa fans, but no one has ever called pent city, ballston or crystal city interesting.
You may well be too tired to think about anything but sleep, but you do have more options than the area near Reagan.
I do admit though that there are pretty good restaurants in NoVa, better than DC!
