This is what we found on Wikipedia regarding the Horse Riding with Open Buffet Dinner & Shows:

Dollywood is a theme park that is jointly owned by Herschend and country singer-songwriter Dolly Parton through her entertainment company, Dolly Parton Productions. It is located in the Knoxville metropolitan area in Pigeon Forge, Tennessee, near the gateway to The Great Smoky Mountains. Hosting nearly 3 million guests in a typical season from mid-March to the Christmas holidays, Dollywood is the biggest ticketed tourist attraction in Tennessee. It has won several international awards.

In addition to standard amusement park thrill rides, Dollywood features traditional crafts, food, and music of the Smoky Mountain area. The park hosts a number of concerts and musical events each year, including appearances by Dolly Parton and her family as well as other national and local musical acts.

The theme park is the anchor of Parton's 150-acre (61 ha) Dollywood amusement destination, which also includes the 35-acre (14 ha) sister water park Dollywood's Splash Country, the 20-acre (8.1 ha) Dollywood's DreamMore Resort and Spa, and the 5-acre (2.0 ha) Dolly Parton's Stampede Dinner Attraction.
