We woke up at 4:30am for the 6:30am departure of our Washington DC tour from Williamsburg. Our first stop was at a large mall near the Pentagon for a quick bite to eat and restroom break. Next was Arlington Cemetery where we took a walking tour to the Tomb of the Unknown Soldiers and saw the changing of the guard ceremony. Our guide, Matt, was pleasant and informative. A trolley ride was available for a fee, but you had to do a lot of walking in 90+ degree weather to stay with the group. We managed, but some older folks in the group were struggling a little. We also stopped at the Lincoln Memorial, Capital Building, FDR Memorial, Korea Memorial, Vietnam Memorial, Marine Core Memorial, and White House. We got a 2 hour break to roam on our own. We got to see the Natural Science Museum, which was awesome. The bus had an issue with the ac in the latter part of the tour, but they managed the situation flawlessly without inconveniencing the guests. We got an extra shopping stop while we waited for a replacement bus. Overall, it was a long, fun-filled, informative day. This was the perfect way to see DC in a day! No way we could have seen all this on our own in one day. Highly recommend!
