Find yourself a Captain George's there and enjoy all-you-can-eat seafood buffet. There are several in that area of the east coast, and one in Norfolk, if I remember correctly. I think the price has gone up to $25/person, but it's definitely worth it for the large spread they have.
Also, if you have a bit of time to drive, head up to Annapolis, MD. Cool little seaside town. If you have even more time, try to get up to the southern part of Pennsylvania and cruise through Amish country. Definitely a must-do if you can get up there.
The DC/NOVA/MD area also has a tremendous amount of Revolutionary War-era sites to take in. Even if you aren't a history buff, a lot of it's pretty interesting to see.
