Sure! When I got off the Hogwart's Express, this is the is
route I took to get on the ride. I didn't need to stow anything in a locker and I just wanted to see if the single rider line was open before I got in line. There was nothing marking this as an entrance, I just noticed that the queue snaked around there and I wanted to see how far back it went. That's when I noticed that there was no chain, fence, or any barricade to prevent me from walking past the lockers and getting into the single rider line. I'm not sure if I was supposed to do that, but it was so chaotic, hectic, and crowded that no one noticed or said anything.
In the very middle of this
picture, there is a recycling bin with a blue lid. Directly above that to the left you see the man in a blue shirt? That's where I basically walked in and was able to get into the single riders line.
