If there is a FastPass+ that you weren’t able to get or a restaurant reservation that you didn’t snag, keep checking back. Things come open all the time. While you still might not be able to get it, there’s a chance that you will. The My Disney Experience App is great for this, because you can check for openings while you’re standing in line at the grocery store or waiting for the movie trailers to start (while the lights are on). If you still don’t get the reservation, don’t fret too much about it. There’s magic around every corner at Walt Disney World. You’ll have a fantastic time, even if you don’t eat at Be Our Guest Restaurant or ride Avatar Flight of Passage.
