if it was a keys to the kingdom tour or backstage magic which is also escorted by a plaid they wait, the VIP does not.VIP is not straight to the front. I know this because I was once right behind a VIP group on the BTMRR fastpass line. They waited just like I did.
But thats what $450-750 per HOUR minimum 6 hours buys you. It is truly a VIP experience
