If you don't mind driving half an hour or so to Newport News, don't miss the Mariners' Museum. It has one of the best ship model collections in the world.
There's also a good hobby shop, Denbigh Hobbies, in Newport News. The owner, Dan DePiero, is an old friend of mine. Ships aren't exactly his specialty, he carries a good assortment of kits and modeling supplies.
You also might want to check out Ft. Monroe, in Hampton. Tidewater Virginia is a fascinating place. The downside is that you find yourself driving around a lot in order to see it. And Tidewater drivers are insane.
Have a good trip!
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
