Yes, it is overused. But if you can point to many other areas of entertainment and tourism and see price increases throughout, it's not necessarily wrong. And it is widely known that the cost of a WDW vacation has outpaced inflation since it opened, so I will admit that part.
But what do we do about that now?
Either suck it up buttercup or go somewhere else, right?
Here's my rationale for WDW going forward:
Is it realistic to expect Disney to actually lower prices when everyone else is raising them? WDW allows for a ton of planning solutions to match various budgets. However, I'm not saying that means some potential visitors won't have to make sacrifices (fewer park days, QS rather than TS, off-property versus on, etc.) or delay their vacation. But again, a vacation, especially a WDW vacation, is a privilege. For example, when I grew up in the late 80s and early 90s, going to WDW meant staying off-property, my bed was two chairs pushed together, and we did one day at MK. So, I can't even look at that time as being better than what my boys are experiencing today when they visit WDW.
If I don't like something, I choose not to do it. My solution with the Dells was a simple one after seeing how expensive it was. I won't go there anymore.
My oldest son once told me he wished WDW was free so everyone could go. I told him if that was the case, no one would go because the experience would be terrible. We all want low crowds, great food, new and really fun attractions, and the best accommodations. But we complain about the cost. I don't know how to reconcile those things where you get all of that with lower prices than say, a hotel off I-94 near Six Flags: Great America.
All I know is that experiencing rides like FoP and RotR and being immersed in Pandora and Galaxy's Edge remind me that my very expensive visit allows me to experience something I can't anywhere else.
