We just got back from Dollywood last week and we had so much fun, even though it rained most of the day. There were so many shows, it was great. If you plan on going back for 2 days or anymore this year (CHristmas is amazing there) it is best to get a season pass. If you do get a season pass, make sure one is gold - that gives you free parking and 20% off all food and other purchases in the park - ours paid for itself in the one day there.
If you have little ones, Boyds has a huge store in PF (4 floors) - you can make you own stuffed animal or "adopt" one. Last year we made our own. This year my 5 year old "adopted" - it was so much fun. She picked out her bear from the nursery and made matching bracelets for her and her bear and then they took her picture with the bear. She has had it since Feb and plays with it everyday and brings it everywear. It was a little pricey, but they took an expired coupon I had gotten from a broshure for 25% off. They also have a great restaurant there.
Have a great time!
