Quoted from Fizz:

I love going to Disney world and have gotten really, really good at riding everything and never waiting in line more than 15 minutes for anything, ever. My methods are much different than the "normal" advice you will hear. But the great thing about Disney world is how it has such broad appeal and so many ways to approach it.
Last trip, my kids actually begged me to wait in a long line for seven dwarfs mine train because they had never had a chance to experience the games in the queue.
Disneyland in California has a whole different system but it's also good as long as you know how to use it. We were there over a crowded weekend, didn't wait in lines. Once you learn how to do it, it's a beautiful thing.
