The direct route seems to be about 8 hours. If you want to make a stop for the night about halfway, I suggest aiming for Hershey, Pa., and then heading up to the final destination. If you have the time, you can take the family over to Hershey Park, even if it is just for a quick tour and one of their sundaes. There is a Hampton Inn & Suites close by for lodging. It has a free breakfast and a pool, amongst other amenities.
