<p>Orange Blossom is right in that Foggy Bottom is lovely and convenient, but prices also are sky high. In checking the River Inn for a random March, 2006 date, the lowest price that I got for a double was about $200 a night, not including taxes. If your family is pinched for cash, IMO, staying in such a hotel isn't worth it.</p>
<p>Over the summer, I paid about $85 a night through Priceline and got a 2 bed room for several week nights in Silver Spring, Md., a suburb adjacent to D.C. I can't remember the hotel, but it was about a 15-min. walk from the subway, about 1/2 hour by car to Georgetown. It was far from glamorous, perhaps a one star, but fit our budget and was reasonably safe.</p>
<p>Over the 4th of July weekend, for about $65 a night through Priceline, I got a three star or so hotel near Key Bridge in Northern Virginia (about a 10 min. drive to Georgetown). The hotel also provided shuttle service to the subway, which can save lots of $ on parking hassles and high parking costs. D.C. is a very hard place to find parking, particularly affordable parking! The hotel lacked the sophisticated charm of a River Inn, but was still attractive and comfortable. </p>
<p>As I mentioned before, on weekends and holidays, hotel prices can go down in D.C. because of extra rooms due to the lack of business travelers.</p>
<p>On other trips to D.C., I've saved $ by flying into BWI and then getting a hotel near the Baltimore-Washington Parkway that runs D.C. and Baltimore. There are some hotels like, I think, a Hampton Inn that are walking distance from the subway or commuter train. One also can drive into D.C. The hotel prices are much cheaper than they are in D.C. even if one has to pay subway/train or parking fees.</p>
<p>One also can save money by staying in Gaithersburg, Md. or parts of Northern Virginia that aren't as close as Arlington or Alexandria. Rent a car and drive in.</p>
<p>I lived in D.C. for 10 years, travel there at least once a year and spent a summer there a couple of years ago. I tend to know the cost efficient ways of traveling there. :)</p>
