Magic Hours do exist in the Magic Kingdom park, in Discoveryland and Fantasyland, which means half the park can be done in a morning before the plebs arrive...
Then you can position yourself to join the massive crowd to BTM...
As for Crush's Coaster, I did maintain that it should be ridden first, though I'm not too sure about the affect of Toy Story Land on it on a busy day these days... It could well be that it's settled as I've had to queue the 90 minutes with the whole thing full... Not fun...
