It’s been circulating all morning. As you may be aware, you need to board a monorail or a boat to get from the ticketing and transportation booth to Magic Kingdom and or to and from Epcot, depending on where you park.
There have been plenty of moments when the monorails have either been breaking down and or slowing down. I think it’s definitely been in talks to replace the old ones. But this is just nuts. I’ve never once seen a door open and just not close, nevermind cast members NOT seeing an open door and just allowing it to go. It had to have happened while it was en route to the next destination, but you’d think the drivers would get a notification of it and stop. I can’t imagine if a child or anyone would be leaning on it at the time, even though Disney always urges not to.
