DC's a unique city because the district line ends well before the urban area does.  DuPont Circle is probably the best urban area in the district.  Other good urban areas outside the district are Rockville/Bethesda, MD (just northwest of the district) and Tyson's Corner VA (this probably requires a car).  Crystal City has a good concentration of hotels but very few providers, and I see lots of girls staying near BWI, but someone else will have to fill you in (that's more like Baltimore than DC to me).

Well, there are a couple options. I suggest the Dupont Circle or Woodley Park areas of DC. There are restaurants, nightlife, shopping within walking distance and are very easily accessible from the METRO (The DC light rail).

Ooh, ooh! Pick me, pick me!

DC and the surrounding suburbs are all very different from BWI, which is somewhat isolated (there is Baltimore's Inner Harbor). You'll have to get info from the ladies on the difference between the areas.

For me, I know I can't make DC or the 'burbs...

Don't overlook Foggy Bottom !!

Foggy Bottom is a cool area and there are reasonably priced hotels. There is a metro stop handy for getting around town. Any area of a city that shares a name with a beer has gotta be a fun  place lol

It is adjacent to GW University and there are many local sites to see if you want to get out and about.

Oh - Good Lord!  I just noticed how *cute* you are!  Do tell us when you are visiting!
