Hi, we are from Uniontown, just a bit south of you and while we have driven straight through, we have also done the leisurely travel and see some stuff drive. Our traditional stops, because we usually pull our trailer are Wytheville, Va (many national parks) and Point South, SC (lowland country jump point). However, when we don't have our trailer we tend to drive farther the first day to Statesville or Charlotte, have a nice dinner and then the next day to Savannah - awesome city, expecially if your girl is a girl scout (and even if not), or you could also try Tybee Island (east of Savannah), nice quiet beach city with great lighthouse, or St. Augustine (another great tourist city don't forget the San Marcos monument) We have loved all of those. All of the Ga south cities give you lots of Mickey time the last day as you get there pretty early in the day.
BTW, ITA with logansmummy!
FYI, for those of you trying to give stops when coming from PIT you don't hit 95 until the I26 junction down in SC, so you do go through Charlotte (while on 77) and Columbia (at 77 to 26 jct). You will not hit Lumberton as that is too far north on 95, although I agree it was a nice stop city, but without much to do.
Oh, and don't forget to watch your speed on 19 (in WV)through the towns - major speed traps, but well worth the shortcut in time even with the slower town speeds.
