Tip: Plan around the parades at Magic Kingdom.

When you enter the park, pick up a copy of the times guide and make note of the parade times, even if you don’t want to watch the parade. If you have no interest in watching the parade at Magic Kingdom, make sure you are in the area of the park you want to be when the parade starts. Traveling around the park, especially around the parade route, becomes next to IMPOSSIBLE. I was at the Haunted Mansion and needed to go to ride Splash Mountain because I had a Fastpass, and it took me at least 20-30 minutes to make that short trip simply because of the parade.
