We're looking to camp near Great Smoky Mountain National Park in August. I've seen Greenbriar Campground recommended often and I think it looks pretty good, however, we're also traveling with my parents and they think it's too expensive. They would rather stay in the National Park to save money, but my husband and I would prefer to be outside of the park so we can have electricity and more importantly, showers! (We'll be staying 5 nights). We want to do some activities in Sevierville, Pigeon Forge, and Gatlinburg, so somewhere in that area would be best. Are there any happy mediums that are good campgrounds but not more than $50 per night? We prefer electricity but water isn't necessary. We also have 2 kids, ages 9 and 6 so a playground or kids activities is a bonus! Thanks!
