Looks like we'll have four full days in the area. We'll probably do the three-day ticket thing, with two days at Dollywood and one day at the waterpark. The final day is up for grabs. Maybe the alpine slide at Ober Gatlinburg plus the usual Parkway tourist trap stuff.
We're going to try to soak up atmosphere, though, so one day is not going to be enough I suspect.
If you're going for more than 2 days, I'd recommend looking into the Gold Season Pass. First off, it's not too much more than the ticket price for 2 days. Second, it includes free parking ($7, and you get the $7 back from the first day that you have to pay before buying the pass).. so that saves you $14 right off the back. From there, you also get 20% off all food and merchandise in the park. With all the good food (the steaks, sausages, cinnamon bread, and ice cream!) and any souvenirs, that can add up very fast!
I've only gone 3 days since buying the pass (2 at the end of december, and 1 last weekend) yet I've saved over $400 so far - and that's on stuff that I would have bought anyway!
I drove past Ghost Town when driving from Dollywood to Carowinds (We took the scenic route). I couldn't believe it when I saw it. I was thinking to myself, "what in the world is a ski lift doing out in the middle of nowhere?" Then I drive past the sign and I'm "oh shoot! Ghost Town is here?"
Too bad it was closed, I really would like to try out that park.
