Look for a blog post soon. We’ve released an update to the Optimizer that lets you indicate a preferred show time. You’d use this if you signed up for a specific Jedi Training Academy, for example, or if you want to see the second Fantasmic! performance.
Note that it’s a preference, not a guarantee. We’ll do our best to get you to the one you want, but there are times (especially at the Studios), where Disney schedules the shows in such a way that you can’t get from one to another in time.
If the Optimizer can’t get you to the show you want, it’ll try getting you to the next-closest.
More details soon.
