Worth noting: Yes, Disney is steering Annual Passholders toward increasingly restrictive passes with more blockout dates than before. However, I think it's only half true to say that Disney is "pricing out some guests to ensure that those with more money to spend can enjoy the parks on busy days." That feeds a little too much into the whole "class warfare"/ "destroying the American dream" that fans like to moan about.
Sure, guests who can afford higher tier passes are given more access, like it or not. But the existence of those higher tiers isn't just so that those with more money can enjoy the parks more often. The root of it is to help day guests – people like me who get to visit once a year – to enjoy our days without clogged infrastructure, locals camping out for shows I have only one chance to see, and overrunning each park's few major attractions. So at the end of the day, Disney is re-balancing the scales to give a little more preference to families and guests who are making that once-in-a-lifetime trip. Which is a good thing in the end.
