I'd never stayed overnight before. This was a chance to do something different and see if it was worth it. Either for the result or just for the mad fun aspect.
For me, it wasn't worth it. It was some fun, but I probably won't ever do it again. However, I probably will continue to get there early. At least for the more popular celebrity. That's worked very well. Last year I got to the Studios at 5:45am for Ray Park. And I had a time early in the second session. I actually prefer the second session because it leaves the mornings free for character photos before it becomes absolutely unbearably hot.
I imagine that they're probably going to stick with the lines because there's less chance of injury than when they let everybody run down the street. One way to see if they're looking to change things is to see what happens at Super Soap Weekends.
