Accommodations

If you are coming in from out of town, there are many hotel options.
I believe this is the BEST option, and where many other wedding guests are staying.

Holiday Inn, Ballston
4610 North Fairfax Drive
Arlington, VA 22203

This hotel is basically on the exit ramp coming in from route 66 into town and it is only four right turns away from the wedding! 
Right out of the hotel onto Fairfax Drive.
Right onto Glebe Road.
Right onto Wilson Boulevard.
Right onto Lexington Street and you are at Bon Air Park!
