Wouldn’t you like to visit Australia, Costa Rica, or Japan for free?   If so, DC on a Dime has found the next best thing. 

Cultural Tourism DC invites you to visit a few hidden DC treasures – embassies!  Starting today through May 9, there will be events at embassies throughout the city (open to the public) where you can experience the culture of foreign food, dance,  music, and crafts.  The main event, however, will be the “open house” on May 2,  where 30 embassies will open their doors from 10 am - 4 pm.  

Cultural Tourism DC will provide free shuttles on May 2 from 10 am - 4 pm. Three shuttles will leave from 1900 Massachusetts Avenue, NW (Dupont Circle) and will loop Massachusetts Avenue, Connecticut Avenue, and lower New Hampshire Avenue.
