To find the most current information I would recommend going to the MyDisneyExperience app.
- select the upside down teardrop with the circle in it, located at the bottom of the screen
- go to top, centre of screen and click the V beside Wait Times. Change it to 'Attractions'
- Filter the park you're interested in (upper, left corner)
- click 'Show List' (upper right corner)
This will display every Attraction in the park you chose and it's status of open or closed.
If you want to find out about shows, choose 'Entertainment' rather than 'Attractions'
- when you select 'Show List', one option will be 'Temporarily Unavailable Entertainment at Walt Disney World Resort' and this will display every show on property that is not currently running.
