What MD said. Another aspect of the AP mentality to keep is Fastpass knowledge. A small amount of Fastpass planning goes a long way on those crowded days. Just take it slow, don't go with any expectations, and you'll have a good time. Oh, and if you end up anywhere near the hub for fireworks and want to head to the front of the park, just before the snow ends, head towards Coke Corner, they open up the back-stage walkway and you get to go right around the insane mob that's till mesmerized by soap.
