If you guys haven't booked a room yet...forget staying near the game. Rooms are 3-4 times the normal price. Instead you might look at towns 30 miles away. If you are coming from Atlanta you might try the Toccoa/Cornelia, GA area. It looks like it is about 30-40 miles west of Clemson. Rooms are 25% of the rates charged in Clemson. http://www2.countryhearth.com/hotel-details/ch-toccoa-ga
To add to that. Southwest is now booking through the end of October to Greenville, direct flights:
$89 1 way from DC
$111 1 way from Chicago
$144 1 way from Houston
I have a lead on a potential tailgate/parking spot. I will hopefully have a definitive yes or no by Monday. Would have plenty of room to accommodate all of our parking and tailgate needs.
