I just went on a southern roadtrip with my husband, and our last destination was Gatlinburg (for his birthday)! I loved it, it was completely bonkers. We had breakfast at Pancake Pantry and spent the day playing mini golf (there is a lot of mini golf, I recommend the historical one, its actually pretty educational). There's an amusement park in the mountains, I think, unfortunately I couldn't go because the husband's afraid of heights. But I would recommend taking a mountain hike if the weather's good, the area is beautiful. And if you love kitsch, you'll appreciate Gatlinburg.
