I feel like the problem with Orlando is that, for so long now, it was the number one destination for theme parks. Nowhere else in the world rivalled it, so it was a bit like, why should we care.
Recently, we've seen a number of high quality, unique attractions popping up all over, that which rivals the likes of Disney and Universal, and all of a sudden the Orlando parks were like '****'. They had to massively rethink what they were doing and sort out some upgrades and fast. They let the parks fester because they didn't NEED to make them any better, they were already the best, and now things are happening to change that.
