I haven't been to Dollywood since 2000, but I'm looking forward to going in a couple of weeks. Especially with everything that's been added since I was last there, I'd definitely have to agree that Dollywood is worth every penny. It's an absolutely beautiful park in a beautiful setting.
Also, remember that if you enter the park after 3pm, you can get in the following day for free. That's like a day and a half for the price of one. Season Pass prices are also very reasonable.
I can't wait to ride Mystery Mine. That's one of my most anticipated new coasters this year.
