Mariott Crystal City and Mariott Crystal Gateway usually have very good weekend deals. They are only a few blocks from each other and there is a Metro station next to one of them (can't remember which).

If I was going right now I would make the new Air and Space annex a must see. Also, the gem and rare coin exhibits at the Smithsonian are must see as well.

I recommend flying in to Reagan National and use the Metro and cabs for transport. You can save a bit of money flying in to BWI, but transport from BWI to DC will offset the cost savings, so Reagan National is IMHO a better choice.

If you fly into BWI, there's an express bus that runs to the Greenbelt station - you can take the Green line right into DC...

Plus, if the weather is nice, there is a certain "WOW factor" when flying in and out of DC with all the Memorial Buildings in plain view.
