Be aware of the many speed limit changes on route 301, in the past it was notorious for speed traps. It has been several years since I drove from PA to the villages, so any info i have would be out of date, but when I did, I went from Allentown to Harrisburg, then 15 to 270 (Frederick), then 495 to 95. This avoided, the whole Philadelphia to DC route.
Hope this helps.
