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.
