As of April 10, 2016, the following enhancements will be available when making FastPass+ selections:
1. You will now be able to choose individual FastPass+ experiences and times. This means you have more control over choosing your FP+ times and no longer need to make all of your selections for the day at the same time.
2. You will be able to book fewer than three FP+ experiences -- you're not required to book three at a time.
3. When you have used your first three FastPass+ selections, you will now be able to make an additional FastPass+ selection via your mobile device on the My Disney Experience mobile app. (In-park kiosks are still available, however.) Once you've used a fourth FP+, you can select another, and so on.
