I was in Pigeon Forge on Friday-yesterday afternoon. I found it interesting that while I was at Dollywood during the Passholder Preview was that Dollywood was going to be delayed a few weeks. What I found interesting about that though, was that everything in Pigeon Forge and Gatlinburg were operating as normal. Though the plan to be at Dollywood on Saturday was changed, I ended up hanging out in Gatlinburg (with thousands of people). I went to Anakeesta and visited several other locations surrounded by people. On Sunday, everything in Pigeon Forge was essentially as busy as it normally would be. Yesterday, you could tell that it was slowing down.
In terms of park operations, it seemed silly to me that Dollywood would not be open as scheduled at least for the weekend. In terms of health, I get it.
