Well, wasn't this just a handy thread! I will be heading for DC myself in another week and a half, and will also be staying in Crystal City, though at the Hyatt instead of the Marriott. All of this information has been so helpful!
I do have a couple of questions, though...I will have about 6 to 8 hours on Tuesday to cram in as much sightseeing as possible. Is my best bet to hop the Metro and head to the National Mall? Or are there other not to be missed sites? I was thinking I might start at the Smithsonian Castle, but then what? Head for the Capitol? The White House? The Library of Congress? I'm pretty open to ideas for making the most of my one totally free day! Oh, and any must try restaurants?
Also, does the Metro sell anything like a one or two day pass? If so, would those be the best options? I for sure have Tuesday open, but not sure about Wednesday...I probably have some time in the evening, but that would be about it. Heading back on Thursday.
At any rate, I am totally looking forward to trying out my brand new Aeronaut and Co-pilot, which should arrive this Tuesday, giving me a week to test pack. I know -- the Aeronaut is probably overkill for such a short trip, but I've been wanting one for EVER, and since I suddenly find that I will be making several trips over the next few months for work, I thought this would be a good justification to finally bite the bullet and order one. Between the Aeronaut and the Co-Pilot, I am looking forward to no-checked-baggage Nirvana!
