There is a free service you can use called www.meetways.com that allows you to enter two addresses and then a point of interest and it will give you the exact mid point and what is around it that you want to do. When I travel and need to find a good place to stop halfway I use it and just put in hotel to figure out a good place to stop. Hope that's helpful.
Gatlinburg, Tennessee, is not the halfway point between Indianapolis, Indiana, and Myrtle Beach, South Carolina. The halfway point is generally closer to areas in Kentucky or Tennessee, but Gatlinburg is located further southeast from the direct route. While it is a popular tourist destination, it's not strategically located for a midpoint stop when traveling from Indianapolis to Myrtle Beach.
