I have been several times over the years, but not recently. I was last there in the early 90s. Dollywood is basically an average quality amusement park or slightly less so. Also if you are interested from the perspective of being a Dolly Parton fan you may be disappointed as it is not overly themed around her. You certainly will not see her performing there, her cousins or some relatives maybe. The park certainly has a country/country music type theme, but other than her picture on the billboards and signs and maybe a small attraction or two about her specifically you wouldn’t know that Dolly Parton owned the place. The shows that are there are very much second rate in my opinion…not that I’ve ever seen a broadway performance at any amusement park… Maybe things have changed.
Having been there I personally would not leave the AT to go nor recommend any one to do so. But then what one likes another doesn’t and you may absolutely love the place…if you found yourself taking zero days in Gatlinburg though it might be worth your time, there isn’t much in Gatlinburg worth doing (the aquarium is good though).
