Bump for a good question! Also, I'm wondering if you can skip doing the backlot part of the VIP experience? Seems kinda lame, and a time waster to me. If I lived more local, maybe I'd be more inclined to take the tour, but I only get to come down maybe one a year from Washington State.
I have been to 2 HHN's (2011, 2012) and both times did the Day/Night pass. The crowds on a Friday or Sat seemed to prove to much with this ticket level option. And for people in their 30's and 40's, waiting in 2hr lines for mazes just isnt't cutting it anymore.
So I am happy that I will be trying out the VIP this year, but want to make the most out of it. My main interests will be: The Mazes, The rides, the "free" parking, and "free" food and drinks.
