I’ve stayed at the Greenbelt, MD Marriott before. But it had been a couple of years. What a change. All rooms completely redone. A great government rate that includes free wireless, free breakfast and a $20 credit in the restaurant for dinner. At check in they gave me a complimentary welcome drink on the spot (hot chocolate and Kuala) and the next day it froze over and someone on staff scraped my window of my car. One of the best hotels I have ever stayed at in the US.
