There is really not much to do at BWI
. Its pretty far from anything, even the MARC station is a bit of a bus ride away. Either way, 2 hours is not enough time to be messing with trains and the such. At BWI
there is like one restaurant that is pretty dumpy, at least the last time I was there it was. There is fast food but a lot of it is behind security and I have never been to the SWA side of the airport. In between the international terminal and the domestic terminals there is this history of BWI
as well as Maryland on the wall with cool photos and other information. Also, there is this observation thing that is inside the terminal with some cool airliner bits and pieces and the such upstairs. Pardon the vagueness of this but that is pretty much what I remember.
