Hi Layla!
It's always nice to see visiting providers! I hope you enjoy your time in the area.
(Please excuse any typos, much of this is copy/paste)
For touring here, I would recommend spending a few days in D.C. and a few days in Tyson's or Arlington, VA. The most popular places to host in D.C. are typically Dupont Circle or Downtown D.C.
If you can, I would also recommend visiting the BWI airport area. Colloquially, these 3 are collectively termed as the DMV - but each area is fairly distinct in terms of client base and accessibility, though there is crossover. As an added bonus, if you visit these 3 areas you can post ads for your dates in the three respective locations (using the D.C., Maryland, and Virginia ad boards). Doing so will increase your exposure in multiple markets. You do not need a car to visit here; Uber, Lyft, and the WMATA metro rail + bus system should suffice for your transportation needs.
In terms of places to go, there are activities and places of interest for anything you love. You did not specify any hobbies or interests in particular, so this is just give a broad overview.
Of course, you can take your pick of any Smithsonian on any almost any subject that you find interesting. If you like art, I would suggest the Phillips Collection, the National Gallery of Art, or the Freer Sackler Gallery. The Hirshorn Museum and National Building Museum often have very interesting exhibits. If you like sports, D.C. boasts an extensive array of professional teams. For live theater, the Kennedy Center is a focal point of the arts scene. However, we have smaller theaters like the Warner Theater, Shakespeare Theatre Company, and Wolly Mammoth Theatre. If you enjoy live music, I would suggest looking over the schedules at the 9:30 club, U Street Music Hall, Blues Alley, DAR Constitution Hall, The Howard Theatre, The Anthem, Clarendon Ballroom, and the Fillmore Silver Spring.
Lastly, for restaurants, it would greatly depend on the area you are in. D.C. obviously has the widest selection of cuisines. Again, it would be helpful to know what type of food you enjoy.
On the higher end of dining experiences, I would suggest MiniBar, Blue Duck Tavern, Metier, and Kinship - you should make reservations ahead of time if you would like to visit any of them. Some of my other favorite places are Bourbon Steak at the Four Seasons, Filomena, Sushi Taro, Izakaya, Jack Rose, 2 Amys, Ghibellima, Barcelona Wine Bar, and Iron Gate. Some new restaurants to the D.C. scene that you may enjoy - Nobu or Kith and Kin (make sure you check out the Waterfront if you have time- it's so nice!) Denson's Liquor Bar is a great hidden speak-easy style place. I also love Ice Cream Jubilee and the butter cake at Del Frisco's Double Eagle is absolutely made by the hands of agenls.
If you favor a sort of party-while-you-eat experience, perhaps visit RPM Italian, Toro Toro, or Marvin. For lively bars try Eighteenth Street Lounge, The Park at 14th, The Graham rooftop, or POV Terrace at the W hotel downtown.
In Tyson's Corner, I love Wildfire and often grab drinks at Eddie V's (they have live music and a nice bar, though the food usually leaves much to be desired). There is a Season's 52 there as well.
Unfortunately, I cannot speak to places in the BWI area. I usually order room service wherever I am there.
Should you choose to spend some down time relaxing, I would recommend the Spa at the Four Seasons or Equinox Spa at the Ritz Carlton.
Feel free to email me if you would like recommendations for more specific things to do/places to stay/restaurants to eat at.
