Just saw this thread. I've been out of town on vacation. Hopefully not to late to help out. Since you are staying in Pigeon Forge, there are a couple obvious places to check out. Cade's Cove of course, which is closed to cars until 10am on Wed. and Sat. mornings. If you have a bike it's a great time to get an early start and avoid the traffic. Otherwise the earlier the better in the Cove. Any of the tribs of the Little and Little Pigeon Rivers are worth visiting. That includes Elkmont, Tremont, Greenbrier, and the Roaring Fork Motor Road. Climgman's Dome is always good for sunset as well as other pullouts higher up along US441.
Another stream worth checking out is Big Creek, hike up as far as you like for nice boulder gardens and pools. You can add that to a visit to Cataloochee Valley to see some elk.
If you have time take a drive over to the Blue Ridge Parkway which starts near Cherokee on the NC side. The best views begin about 8 miles up and continue at the higher elevations most of the way to Asheville. As with most landscape photography, mornings and evenings are best.
If you are a hiker, let me know and I can suggest a few hikes that might be of interest. Hope this helps and have a great trip.
