Let me say that Dollywood is one of the best bargains around. If you first enter the park after 3pm, you can return the next day using the same ticket. That's really two days for the price of one. While this is plenty of time to spend at Dollywood, you have the opportunity to spend it on your favorite rides.
For those connected to the military (my husband is retired Army), the entrance price is half off. Fifty percent of the regular admission price and you can spend two days at the park. An excellent deal!
There are many standard water rides. Nothing too outrageous or spectacular. The shows are mostly so-so, but we did see an excellent singer (and we don't do country and western). The Purina dogs were enjoyable.
Dolly Parton was a forerunner in establishing organizations to protect the cultural heritage of Appalachia. Many crafts and artisans are available to be seen.
