Guests will meet at the bus stop on Pennsylvania Avenue, NW close to the corner with 9th Street NW, near the National Archives building. The bus will arrive approximately 15 minutes prior to your departure time. 800 Pennsylvania Ave NW, Washington DC 20004
You can cancel up to 24 hours in advance of the experience for a full refund.
Future tourists, my advice is to follow the red light at night, take time to admire the monuments instead of snapping photos the whole time, and listen to the tour guide as they will explain what to do.
I would definitely recommend this tour to friends and families.
