I am planning to stay in Gatlinburg with my wife and 2 preschoolers the week of new years for a few days. Our plan is to enjoy the town and then drive south (3.5 hours?) all the way through the Great Smoky Mountains and into GA to a little town called Hartwell for a wedding. My biggest worry is the weather and road closures. I was hoping someone could throw some tips or advice or ideas my way to help make my trip a fun and safe one. Thanks in advance.
