Might be traveling to DC for a week of so in the next few months. Looking to make it a week-long trip, so I'll likely stay 5 nights at the Sheraton Pentagon City or Arlington Westin or Le Meridien on points, but thinking I'll also use my free night cert while in town. Any suggestions?
BTW: When I'm in the area, I typically use free hotel shuttles and the metro to get around, so something far out won't work for me, but anything with reasonable metro access (like a hotel van drop-off, etc.) is good.
