When we got off the gondolas, we went to the front to ask, with our friend who had recently had knee surgery and was walking with a cane. We were told in no uncertain terms to "go to the back of the line!" without any question of whether we were with the race. When I questioned that my friend would have to stand for that long (he's been renting ECV's in the park, but can't park hop with them) they agreed to let him wait for a courtesy wheelchair first.... One time when we arrived, there was a queue all the way past the boat dock that we initially thought was the general admission queue, but one of the guys in line near us walked up front to check it out and it turned out that it was a separate queue for a special group. So we were able to walk around them and enter. I'm not sure if you would have been able to bypass that insane queue if you had tried.
We found out as we made it back up to the front that they were letting folks from the boat dock bypass the line and enter. And like I said, once we got to the front, they were announcing "non-race participants" can bypass the line. I'd say 20% of the people around us in line were not part of the race and none of us were happy we'd been made to wait just to find out we really didn't have to. It was really poorly managed.
