One can find lodging, entertainment, and food in Gatlinburg, Pigeon Forge, and Seveirville. There is a short trip of a few miles between Gatlinburg and the other two cities.
Gatlinburg is the place I recommend as a base. There is ample food, attractions that are family friendly such as miniature golf, museums, and arcades, and even a space needle for getting above the town. A ski lift moves people up to an area called Uber Gatlinburg. The Aquarium of the Smokies is itself worth a visit. It has an advantage in that it has much in walking distance from the strip, or main road.
Pigeon Forge and Seveirville are different. They offer an abundance of food and entertainment, but walking from place to place is not like walking in Gatlinburg. Things are separated, whereas in Gatlinburg one is always feet from an attraction.
But, Pigeon Forge is home to Dollywood, and Dolly Splash. Also, the Dixie Stampede offers a unique dinner and western show. Many other restaurants in the area offer dinner and a show as well, but these are not western themed with horses featured in the entertainment. Some feature comedy, some others feature singing.
I recommend the food, and the entire experience, at Apple Barn. There, set in an apple orchard, are two restaurants, an ice cream parlor, and gift shop. The theme is apples, and it is a great place to purchase apple butter.
In Gatlinburg breakfast at Flapjacks is hard to beat. They serve a haughty meal of tasty breakfast staples. The menu offers so many wonderful choices it is difficult to decide what to order.
