Another must do, as my Capt. Flint has said in a previous post, is Colonial Williamsburg, Virginia. It was such an awesome destination...
Ah, the weapons are most impressive! You can purchase a ticket that will get you into Colonial WillamsburgHistoric area, Jamestown Settlement and (darn, I can't remember the third one...) in the Historic Triagle Ticket. Or, if you are feeling really up to a trip, a 7 day, 5 attraction pass includes Water World and Bush Gardens.

And there is a Campground very near Williamsburg.
