You may want to push further south into Alexandria; unsure about availability but some choices are:

Hilton Alexandria Mark Center (just of 395/Seminary Road)
Hawthorne Suites (Van Dorn Rd, just off 395 as well)
Comfort Inn (Van Dorn Road, just off Beltway entrance)

My understanding (I just moved here a few months back) is that you want to stay inside the Beltway and north of the mixing bowl (the convergence of 95, 395, and 495/Beltway) because that gets UGLY during rush hour. An early morning commute from this area (non-HOV lane) takes approx 40 mins to get to Georgetown.

Alternative -- drive to Blue Line metro and ride into town. You can change to Yellow after 1 stop (King Street) or Orange Line at Rosslyn (the stop closest to Georgetown) or Red (Metro Center). Unsure where your ultimate destination is. You can download a metro map at www.wmata.com and plan a trip online as well to get a feel for trip times.



Happy Hunting.
