i know this thread is a bit old, but I did the VIP tour back in 2005 and it was totally worth it for me (not to mention I sold off my AP voucher and gained back some of the investment).
just about the only thing we didn't do on the tour was the makeup and fx show - the guide felt it was worth skipping. i did see it later, but i probably could have gone without it. i was able to ride both jurassic park and ROTM multiple times as well.
it's been revamped since then for the better so i'm planning on doing it again in april.
