A few days ago, a Disney World visitor shared this panic-inducing video on Instagram.
The Monorail, which was leaving Epcot and en route to Magic Kingdom, had a door open. It was most likely from some kind of faulty electronics, but even more concerning is that no cast member noticed the door open as it was leaving. That's terrifying. Since then, Disney has posted "Do Not Lean" signs on the door, but still.
Looks like I won't be taking the Monorail for the foreseeable future.
