This could actually end up being a good thing for me, because I don't really care if I ride many of the headline attractions. I might be able to pay to immediately get on the handful of rides I actually want to do without having to wait in a long line, and then can spend the rest of my time doing my other favorite attractions that hardly ever have long lines, or even lines at all -- Carousel of Progress -- and just wandering around.
That doesn't mean I think it's a good system or that I'm happy about it, though. It sounds like it will be terrible for your average family.
