I would say that knoebels could be anywhere from 1.5 hours to 2 hours from dorney depending on which way you go. Even though I live somewhat between them I would still probably have to look at a map to see the shortest route between the two. Dorney is right off the turnpike/309 and Knoebels requires a lot of back roads. Anyway you go I couldn't see it being anymore then two hours.
