I haven't read all of the responses, but I believe that there is a middle class price out going on to some degree. When I first went to WDW in 1998, costs were lower, but so was our income. A trip to WDW costs a larger chunk of our disposable income back then.
Fast forward a decade. WDW's advertising and target market shifted. You start seeing ads on TV for this incredibly cheap and affordable trips to WDW. If my memory serves me right, they were advertising a 5 day trip for a family of 4 for less than $2000.
So what happened? The floodgates opened. Everyone was packing into WDW. The parks use to be crowded, but there was a whole new level of people packing into the parks. It was insane.
But something else happened. The "specialness" factor dropped. Big time. Since everyone could afford to go to WDW, they did so. In great numbers. New resorts continued to be built to accommodate them and the already stretched resources (such as bus transportation) was stretched even further to deal with it all.
So fast forward another decade. If anyone has a business background, you will know that Disney's business model is founded on a growth formula. They have to keep the income growing or their investors suffer by not getting the return on their investment like they expect and demand. IOW, they expect to make money when they buy Disney stock. Since they have played out the option of bringing in more people, their only option left is to make more money on the existing traffic that are coming in. So they have chosen to nickle and dime their customers through paid perks while raising prices where they can.
So to me, WDW is doing nothing more than cleaning up from the many years where they made
Disney vacations affordable for everyone. Now the prices are playing catch up. Just as not everyone could afford to go to WDW in the days of old, it is returning to those days where most people can't afford a trip to WDW yet again.
Let's face it. A trip to WDW would not be special if everyone can afford to go. Trips to WDW are still possible for the middle class, but it is also possible to spend as much as you could possibly want on a Disney vacation. If you are going to spend more, you can bet you expect to have a better experience and you expect to do things that are beyond what the masses enjoy.
