I second the motion for Williamsburg, VA. It is only about a 3 hour drive from where we are in So. St. Mary's County. You have Colonial Williamsburg, Jamestown, Yorktown, Busch Gardens, Water Country USA. The College of William & Mary (the oldest public university in the United States, and second in age to Harvard) is right across the street from Merchant's Square/Colonial Williamsburg and is a beautiful campus to walk around. (a little partial there as our oldest child is a graduate of W&M!) Lots of wonderful places to eat, (the Cheese Shop at Merchant's square has awesome sandwiches for reasonable prices). At Colonial Williamsburg, if you don't want to pay the entrance fee you can still walk around the grounds, just not go into any of the buildings or exhibits. If you have any other questions, you can pm if you would like.
