The Dragon Expo will be held at the same time. Here's some info I posted on one of the 1/6 forums:
30 MINUTES FROM MY HOUSE 
and right next to the beach!!!
Hopefully they'll get the word out to all the military around here and those who reenact so they can have some good displays and vehicles.
The hotels are expensive at the beach this time of year, but there's plenty of them (and probably booked up from all the tourists), but there's plenty more within 30 minutes drive (even downtown Norfolk, Portsmouth, and Chesapeake near where the Joe convention was a few years ago) and easy to navigate.
Oh yeah...the traffic is the pits around here.
