We usually stop at Point South in SC, which is right ON the interstate, but has some good size pull-thru sites. It is at mile marker 33 on I-95 in SC.
This is just an assumption that you are heading that way since you don't state your route.
Point South should be about an 8 hour drive since we don't really know where you are leaving from and the FL border is about 3 hours from there since we don't know where you are going to.
