According to the article:
"The price for the cheapest Disney World annual pass with year-round access soared 23%."
I know as a AP the prices have climbed a bit. Yes there are certainly still much more reasonable than for those that have to buy individual tickets, but still comparatively to what APs have cost over the last few years they have gone up by a good amount. I remember paying high $200s for seasonal blackout passes, and now the 'Silver' is around $415. Parking is now included, but the work around for that in the past was buying (1) premium pass and the rest regular. A 9 year old doesn't need a pass with free parking
I don't mind WDW raising prices to remain as a premium experience park. In the past my wife and I had season passes at one of the old Paramount owned theme parks and the season passes were prices at a point (roughly $79 for the season), that just about anyone would buy and go to the parks. This included droves of kids loitering in the park in masses acting like idiots and really detracting from the experience. I don't see as much of that at WDW because based on the price point, you really have to want to be there to spend that kind of money.
