Understand the fast pass system. There should be blogs online about it. Don't get fast passes for rides that are not worth getting it for. The main ones where fast passes "run out" are Radiator Springs, Guardians, Space Mountain, and Indiana Jones. Note that the two parks are under two different fast pass systems and if you stay at any of the Disney hotels, I believe you can request specific fast passes. Try and get into the park first thing in the morning. As soon as you get in, bee line for a fast pass to one ride, and wait in line for another. Some rides such as Toy Story are not part of the fast pass system. While waiting in lines that are 1 hr+, have a friend to go across the park and get more fast passes while you wait. Also, the time window for these passes are not super strict. That being said some cast members can be particularly annoyingly strict. Good luck!
