Traveling to Cherokee NC area campground

I would recommend you stay on 74 (great smokey mountain expressway) to exit 74, and then follow the signs for the casino, that's the best way to go. 19 is too curvy and long, for my taste, 74 is 4 lane the whole way.
What campground you staying at? we stayed at the KOA a couple weeks ago and it was nice.

thanks safe and happy travels!
