Washington D.C. Is this a good Plan for 3 days? Hotel? | United ...

We will have a car. We found a Marriott close to the East Falls Church Metro station (orange line), but haven't booked yet. Is that area okay. Hotel reviews were all good. How long does the metro take to get into DC from that location? ... Is it better to book the ranger show or the one act play? Then hopefully start on museum of Natural History. I have a reservation at 5:30 for National Archives. Saturday: Drive to Mount Vernon. After lunch visit Arlington.
