We've booked a return train through Amtrak, arriving around 8am, leaving just after 10pm, and would love some suggestions as to how to spend our day.
We're fairly active, so we're happy to walk the distances, but it's hard to gauge how much you can really fit in a day anywhere without having been there before. This will probably be the only day we'll have to visit DC, so we'd love to fit in as many/the best of the sights/museums as possible (while obviously leaving enough time to appreciate them!).
Any ideas/suggestions? :)
