That is on the contractor for not installing properly and Disney will take the heat for it. After seeing how it fell off the wall it looks like they just screwed them into drywall which won't hold anythingLooking at the photo on FB I think the entire bed unit became detached from the wall - wasn’t properly secured to the wall. If I were Disney I’d be having every one of those beds in the Riviera checked for proper secure installation. And if there is a weight limit I’d make sure that limit was prominently included in the room description, because small kids aren’t the only people who are going to sleep there.
It’s one of the reasons we aren’t moving into a new construction home closer to my kids’ school versus staying put in our home built 30+ years ago. This house is solid!
