I've been to all three a number of times and agree that each has it's own unique charms. Hershey is the closest and I started going there from about age ten when it was still a picnic grove and you bought tickets for the rides. The funhouse was truly fun with the barrel walk through, spinning disc, and spinning bowl that sadly became too expensive to insure for liability. Dorney Park was pretty good too with the old original rides but some were removed or revamped and the soul of the place was lost.
