Can you provide a little more detail about how the "moves" were done?

"in library mode, it appears unedited. When I switch to develop mode, it appears with complete edits."

In the Library mode you are looking at "previews", not actually the image itself. You may need to update the previews. Select the wedding photos, then in the Library mode, pick Previews from the Library drop down menu and pick one.

I can't verify this will work because I've never seen it on my equipment.

We live in Bryson City, NC, so I'm a little predjudiced towards "the quiet side" of the Smokies. I can only reinforce what others have said about the crowds that time of year. Get there early. There are so many places, but on the TN side, I love Cades Cove ( I think this is closed to vehicles Wed mornings, but check with visitor center) and also the Greenbrier area. The TN/NC border has Newfound Gap, the overlooks close to the top on both sides, and Clingmans Dome. I enjoy closing out an evening at the Clingmans Dome parking lot. Parking will be an issue in all of those areas, but take your time and enjoy. In NC, the Deep Creek Trail near Bryson City offers a nice 2.4 mile, 3 waterfall loop. Easy walking on an old road bed. As mentioned Soco Falls is beautiful, but to get a picture like the one shown, you have to go down some pretty steep and slick rocks and there is very limited parking along Highway 19. Any section of the Blue Ridge Parkway (BRP), including Waterrock Knob, has great views. I'll be glad to answer any other questions you might have. Enjoy and come back again!
I forgot to mention the wonderful Cherokee Museum and several shots with authentic Cherokee crafts and art. Also, there should be a lot of elk around the Oconaluftee Vistor Center and now often in Cherokee.

What you might want to do today is join two Facebook groups that I belong to that focus on Photography in the Blue Ridge, you will see images of Northern GA, NC, and TN. Most photographers will note where the image was taken and you will see a lot taken from the Blue Ridge Parkway. Their images will not only inspire you but will give you clues on composition as well as focal lengths that produce the best results.

Both those groups have pro's that contribute and their work is awesome.

If you visit Cade's Cove you will be close to the parkway. You may as well get on the Parkway and head towards Ashville. Not to far in you will come to Hwy 19 near Cherokee NC and with a very short drive you will arrive at Soco Falls, a Falls I have yet to visit but really want to. As you travel the parkway you will pass several overlooks many of which will offer great photo ops. At mile mark 451 you will come to Waterrock Overlook which offers great opportunities for both sunrise and sunset shots. If you make it all the way down to the Brevard area you will have passed several great photo ops, in the Brevard area you will come to Hwy 276, if you head south on 276 you will come to both Sliding Rock and Looking Glass falls. Both of these falls are very close to the road but a steep climb down, the good news is that Looking glass has concrete steps leading all the way down to a low observation deck. But to get great photos of any waterfall you will have to actually get down to the river bed and probably get your feet wet. Something to think about as you plan your trip.

Obviously the image below of Soco Falls is not mine, I pulled it from the web so you could see it.

I have not researched TN but I am sure that there are plenty of waterfalls and a few Grist Mills that you can find by spending a little time on the internet. Anyway, good luck on your trip and for sure don't miss the Parkway.
