Crystal City.  Safe, affluent, little to no LE activity, little competition (unlike Dupont and Tysons)  and best of all.....lots of GREAT shopping and restaurants!

Sonce I work in DC, as many do, it's easy to take a quick cab from work to a DC hotel during the day.  Tyson's is a nightmare for many to get to during the day if you work in DC. Consider that many hobbyists only do daytime appts if they have an SO and can't get out of the house in the evening.

Thomas Circle, Dupont Circle, Adams Morgan, all fun areas with lots of hotels

Foggy Bottom and the Capital Hill/Union Station area.  Tysons has lots of hotels but is strictly a cars-only environment and traffic to & from can be a killer.  But lots of guys don't like riding the Metro so don't like going into the city due to parking $$ & congestion.  Many visiting ladies do a couple days down town & a couple in Tysons.

Vienna (city that makes up a big part of what's considered to be Tysons Corner) are good bets also.

My answer is>>>

I love Tysons Corner. Do not worry about construction and metro...if you are nice (and I know you are!) with a great pic, they come! Its an awesome place for incall, The Marriott is wonderful and Embassy Suites. BWI is nice, tons of hotels and plenty of tourists. Currently, I am in Crystal City and most definately commuters come here without a problem as well as guys in cars. They travel from Tysons, Silver spring MD, DC and Rockville because there is no congestion. You can't go wrong in any of these locations! Good luck

DC traffic is always unpredictable.  If Im driving in from Baltimore, I have to double the allotted time.
