2. Book a Fourth FastPass (and Beyond)
After using your first three FastPasses, you will be able to book a fourth FastPass. Many people don’t take the time to do this, and instead spend more time than necessary waiting in line. By snagging a fourth FastPass, you can skip the line for one more attraction, leaving you that much more time to enjoy something else.
On top of that, a fifth pass can be obtained immediately after that fourth one is redeemed, and a sixth one once the fifth one has been redeemed, and so on. If you stay on top of booking, you may be able to skip the line for as many as 7 or 8 attractions in your one-day visit.
