But good on Disney, I'm glad to hear they're making a move for the customers' benefit.
I Respond: You missed the words "up to." Meaning they don't necessarily "expect" it to be that long, but rather, if the situation arises, that's how late they are willing to keep it open.
Having said that, a wait that long wouldn't surprise me. Here in Florida, on a "healthy crowd" day at EPCOT, the wait time on 'Soaring' often breaks the two hour mark.
