I've Been Going to Disney For 25 Years, and These Are My Best Tips

The best way to maximize your time at the parks is to continue to get FastPasses even after you've used your original three. To do this, once you check in at the first check point of your final reserved attraction, start looking on the My Disney Experience app for a new FastPass, either at the park you're currently at or a different one. Continue to do this each time you check in at the next check point for an attraction.
