I hate to say it but if you don't like it don't go. Stop giving Disney your money.
OR
Realize you are going on OFF-PEAK season. I'm going Sept 15-20, park days of the 16-19th and I fully expected short days (which it looks like my dates they close at 8pm), does it suck, yes but I'd rather have 2hours less than deal with an extremely packed crowds.
Is 1-hour really going to affect your trip? How many rides will you realistic be able to go on in 1-hour.
Disney is a business, as people have said they are trying to maximize profits. You do have a choice when you go, Disney didn't tell you to go in Sept.
