Try the Grand Smokies Resort Hotel. That used to be the Great American where most of us stayed. They always had much lower rates. I always blocked 15 rooms and had a cutoff date of around the Labor Day weekend. That's the one that has the big buffet restaurant in the parking lot.

I looked at the two locations and they are a good distance apart, but going out the side street it would be easier to get there without all the heavy traffic on the Parkway. Looking at a satellite image, I don't see where the host hotel would hold the event.
