We are flying into Greenville and driving to the Whittier area for 3 days. Then driving to Asheville before returning to Greenville to fly home. Since we are driving the interstate on the back end, is there a different route to get from GSP to Whittier? Google Maps is suggesting 107 as an alternative. Fewer miles but longer. Is it worth it or better to just stay on the quickest route? Not sure if this is the best forum?
