Also if you have the time and extra cash you may want to head down to annapolis *spelling*. The women are VERY VERY attractive down in that area, and the overal landscape is nice (depending on what areas of town you hit). I have lived outside Baltimore all of my life and have enjoyed every part of it.
Have a good time and by the way, don't expect to see many O's fans at Camden Yards the night you go. It seems for some reason the Yankee fans overrun the ballpark and it's almost like Yankee Stadium 2 down here........
