Our family, with kids aged 7 and 9 yrs will be flying in to Knoxville in July, on our way to Jellico, TN. We have 3 days before we need to be in Jellico and would like to look around the area. Where would you recommend that we stay? Should we make Knoxville our base? Or should we drive straight from the airport to Gatlinburg or Smokey Mountain? We know almost nothing of the area! We'd like to book our hotels soon, so we welcome recommendations! Thanks!
