Hi there,
You should fly into National Airport (NAD). You can catch Metro
Metro from the airport to the Crystal City. From there, you can walk to the Crystal City Marriott, Sheraton. You can also get a shuttle from the Crystal City Hyatt Regency. Most of the Crystal City Hotels have shuttles to and from the airport where you can catch Metro.
You can get an all day ticket from Metro that will take you to all of the sights. If you want to hang out in Georgetown, get off Metro at Foggy Bottom/GWU ; walk up to Washington Circle and catch the 32, 34 or 36 bus that says Friendship Heights. This bus will take you to the heart of Georgetown. Be sure to get a rail to bus transfer before you leave the station.
The Air and Space Museum is across the street from the L'Enfant Plaza Metro Station. You can catch a trolly from Union Station (also on the Metro line) that will take you to Mount Vernon and Arlington Hospital. There is a amphibious tour called DC Ducks that takes you on the Potomac River past all of the mall sights. The other Smithsonian museums are near the Smithsonian Metro stop and the Holocast Museum is also near the Smithsonian Metro stop.
You can get around very well using Metro. I totally recommend staying in Crystal City because of the underground walkways and shops along with all of the hotels. Enjoy!
