R&R. Go to the Appalachian Trail Conservancy, then go to Hike the Trail, then go to Shuttle List and parking tips. As a veteran of many section hikes, I will be glad to help you out.
I have read some of Shakedown’s journal, he is about half-way there. You should know that by the time that SC has reached Nortern PA the hiking pace will be alot different than someone doing a section hike (like yourself). He may have friends on the AT that have become very important to him and wants to be with them. No reflection on you. But many times people or family that join a thru-hiker for a little bit of time do not always have a great experience hiking.
I would suggest meeting him at a location along the trail near a hotel or hostel, buying him a couple of meals, letting him do laundry, taking him to a movie, letting him re-supply, etc.
