There is almost always a last minute cancellation. Try the Days Inn or Holiday Inn across from the Huddle House(I think its a Huddle.. breakfast house or so sort) at the end of town(Can't remember the road). I always have good luck there, the Holiday is a little more but worth it. I usually try to make the civil war in the spring and the Fast Fords in October, not sure this year but I may ride my bike down there for the day(2 hour ride for me).
Oh and you might want to check out
www.orbitz.com or some other online travel agency, they will tell you if anything is available and you can usually get a better price than just showing up, Good Luck.
