Are there any drawbacks to staying in Tyson's corner when visiting Washington, DC?

My girlfriend and I are taking a road trip to Washington, DC the first week of June. We're going down on a Thursday, stopping in Baltimore on the way down to visit the Inner Harbor, on Friday, we reserved the 10 AM Capitol tour, and plan to visit the Smithsonian museums and the memorials, on Friday, we plan to visit Arlington National Cemetery and Mount Vernon, and on Sunday, we're going to check out and visit Ford's Theatre and the National Zoo and then go home. We're thinking about staying in Tyson's Corner. The hotel we want to stay at is right next to the Tyson's Corner Metro Station. It seems a little less money to stay in Tyson's corner as opposed to in Washington or Arlington. Are there any other drawbacks to staying in Tyson's corner other than the longer Metro ride into Washington (35 minutes)?

I've heard that the hotels around that metro stop are economical plus you don't need a car in D.C. You will need walking shoes.

Now that the metro stop is open, there's no real problem to staying there since you have easy access to Washington. There are shopping malls and restaurants in the area It's not a great place to walk, but presumably, you're only going to be there to sleep at night. It's fine. If you do stay there, the Da Domenico restaurant is excellent. http://www.dadomenicova.com/

Besides the long (and expensive) Metro ride, which will include transfers from the Silver Line, I suppose not. If you plan on visiting Mount Vernon and Arlington Cemetery, though, you might want to stay in Alexandria instead. There's an express bus that leaves hourly (IIRC) from Huntington station at the end of the Yellow Line. You'll be able to catch the Blue Line to Arlington Cemetery. And the Blue and Yellow lines both go to the National Mall where many of the museums are. Or do you plan on driving to Mount Vernon?

It should be fine, now that the Silver line station is open at Tysons Corner. There are two huge shopping malls there, plus a wide variety of restaurants, both within and outside of the malls.
