We landed in DC at 9AM Friday and left at 4PM Sunday, so the trip was short, but we managed to fit in as much as possible in that time. Lehr got us a hotel close enough to see the Washington Monument out of the window, and we walked and took the Metro everywhere.
The next morning we went to Ford Theater which was by far my favorite. We then walked and Metro-ed the rest of the day to hit a tour of the Capital and the Museum of Natural History. After dinner we followed the same protocol (after a quick dip in the pool), and Eli and Lehr hit the Jefferson Memorial.
