It’s a good thing there are plenty of attractions in each Disney park because this gives guests other options when one happens to close.
We see plenty of unexpected closures, like when a ride suddenly breaks down due to technical issues, but these are often fixed the same day. Attractions see a lot of daily use though, so sometimes they need to close for extended periods of time to allow Disney’s teams to do some maintenance. These fixes take a bit longer and one ride has just CLOSED as part of an extended maintenance closure in Disney World.
