My pops and I are planning a trip to DC for late September. We're in the process of setting up a tour of the White House and Congress now. Most of the attractions in the area of the Washington Monument appear to be within walking distance.
So I'm thinking about seeing the WH and most of the monuments day 1, Congress, National Archives and the Supreme Court on day 2 then day 3 at Air and Space and whatever comes up with what free time we have left.
We only have three days, but is there anything we should absolutely see while we are there? I would really like to sneak over to Arlington to the Tomb of the Unknown Soldier. Open to suggestions and thanks.
