Thinking about a day trip to Baltimore before my flight home on Monday (currently in DC). A couple questions....

1) How far is downtown Baltimore to BWI? And how would I get there? (Flight takes off at 130pm, but will attempt to VBD)

2) What is there to do in BWI on a Sun night/Labor Day Monday morning? (Never been to Baltimore before).

Thanks!

EDIT: I meant to say "what is there to do in BALTIMORE (not airport) on sun/mon?" but also good to know if i can stand hanging out at BWI itself ^
