Cedar Fair parks do that already... I went on one many years ago (because my visit to Kings Island was the 5th July, it was busy), which was $300 a head for 8 hours of guided person, instant ride access (including the burdenous row choice, though we only cared about that on Beast and Diamondback) and priority show seating, food, vouchers and a backstage tour of Beast... Certainly got the value for money out of that one...
And it was STILL cheaper than anything Merlin offer, though after a quick search it looks like it no longer exists... But that is how to do a VIP ticket thing...
