2. Coordinate FastPass+ for busy times of the day and the busiest attractions.
You likely wouldn’t need FastPass+ right when the park opens since guests will still be arriving. So you may want to wait until mid-morning to start FastPass+ options since you can get a couple rides in soon after park opening. You will want to use FP+ for the busiest attractions, since even at park opening, there are crowds of people that flock to rides Seven Dwarfs Mine Train at Magic Kingdom and Toy Story Midway Mania at Hollywood Studios. We have waited at the rope for park opening at HS, rushed to Toy Story Midway Mania, and still had a 30 minute wait. If you use FP+ for these rides and rush to rides that will have almost no line first thing in the morning you can fit more in, in a shorter amount of time.
