Days Inn Arlington on Rt. 50. will do a one nighter for around 100.00 per night.
Thanks for the info. Everyone in DC is requiring a 3-night stay.
The Days Inn Arlington on Arlington Blvd & RT 50 still has rooms priced 90.00 to $112.00. It is 2.7 miles from City and they have a complimentary shuttle which will take you to Metro a few blocks away. The will take a one nighter if you desire. Its very plain and dated but is clean. They have a very friendly staff. We stayed there for the last inauguration and it worked out well. Just remember it is very basic.
