Yes, I've been to Great Adventure a couple of times and Hershey once. Having travelled thousands of miles to get to GA I've rented that strange Q-bot thing both times (think it has a new name now) which did make light work of the crowds. And I've got to take my family on El Toro which is one of my all time favourites, to say nothing of Kingda Ka and Nitro which also tick some boxes.
I certainly would like to get Kennywood into the schedule. Would people generally agree that it would be a preferable choice over PKI as suggested earlier in this thread? I haven't been to PKI since the Beast was untamed, can't remember the year, but CP's Mean Streak was in its first season (also untamed compared to my last visit to CP three years ago).
