We will be traveling to Williamsburg the week of Oct 10-17. We would like to take a minimum 2 day trip to Washington D.C. We have heard traffic in DC is heavy and difficult to find parking. We are considering traveling to the Pentagon/Arlington area and taking public transportation to DC. I am wondering if this is workable and what is a good area to find a hotel. We are trying to get tours set up for the White House and Congress. We might want to spend some time at the Smithsonian but unsure how that will work with our very short time frame. If anyone can advise on this plan, I appreciate the feedback. Thanks in advance.
