Man, that really sucks. You've got broken rides at three different parks on the same day, at the same time. And that's really bad luck to have attractions closed hours before the park does, because I've honestly never known that to happen. I've known them to be shut down for a while, but I've never seen any ride at WDW to have an unscheduled closing that's announced earlier than park hours. Or a CM who just shrugged off a concern, or a manager who admitted what a specific problem was -- and to have wait times that far off and no one knowing about it. That's a very bad string of luck, though I'm glad the manager was able to extend your FP for a fixed-time show. Sounds like a real cluster of incompetence and malice there, and I'm sorry you were the brunt of such a set of unusual problems.
Hope the rest of your trip goes better.
