because you already in Washington DC, and live free. you should spend 4,5 days to tour the US capital city. DC have so many things to see. you must not missed.( and you may have friends gurad you, otherwise, just join the day tour still ok ).
from DC Chinatown , you can take a Chinese operated bus company to NYC, the fare is $15 - $20 one way..... very cheap.
because the NY hotel is kind of expensive, you may stay in Downtown, near Chinatown area, there are some ( not bad ) small hotel, clean and safe is all you want.--------- you can find them from local Chinese news papers Ad.,then call them ask for room. ( the room is about $120-$150 a night ).
NYC has very well public transit system, you don't need to join any local tour. you can take subway and bus to go almosts everywhere within the city's famous place and landmarks. get a subway map ( it is free ) from the subway ticket broth, find the places to want for sightsee. that's easy.
also, you can join the tour from local Chinese travel company,to go to Boston, Atlantic City, as one/ two day tour.
you may stay in NYC for 4, 5 days or more , then take the same bus return to Washington.
