As with all things Disney, this has once again become a battle against pixie dusters who cannot abide any factual information that reflects negatively on the Mouse.
While I don't think Tom-level negativity is warranted, it's perfectly reasonable for the average guest to have some concerns about this system given that a major shutdown -- and an emergency evacuation -- occurred in its first week. Disney doesn't deserve the benefit of the doubt until they have months' worth of regular operation without major issues.
Me personally? I booked a Pop Century stay in a few months because of the Skyliner access and I'm seriously considering moving off site instead.
