I second what Denny said. Maryland has a nice campus but College Park is underwhelming. Go into DC. There are a bunch of great neighborhoods.
For a wild night do Adams Morgan, clubs around 14th & K NW or the bars and clubs just south of Dupont Circle around Connecticut and M St NW.
For a classy night go to north or Dupont Circle, Wiodly Park or Eastern Market.
For a fun night got to the 14th St Corridor between P St NW and U St, H St NE between 11th and 15th, or U St NW between 9th and 15th.
For a top notch craft beer bar check out Meridian Pint in Columbia Heights. Great beer will not be hard to find in DC.
Whatever you do, don't go to Georgetown. It's shit. All bros and stuffy people there. I would avoid it. Virginia also sucks. Tons of bros there and it has no soul.
