Here is the thing: things like CBJ overlay add to the Show. Show is one of the four KTTK. Following the KTTK principle has led to the creation of the greatest system of theme parks in the history of the world, by many measures, but the one that is most important to the suits, of course, is the financial measure.
Start to ignore or take away elements of Show, and it is the beginning of the end of the World as we know it. Ultimately, the suits know this. They are continually in a state of having to weigh the expenses versus how much the contribution of a particular element to the Show supports the patrimony of the enterprise.
Show is part of the KTTK, KTTK is what brings the magic. Without the magic, WDW is nothing. When the suits start to forget that, it will bring the demise of the enterprise. So far, they seem to understand that enough to keep brining increasingly large crowds to the World.
I wonder, though, what the trend is with regard to the percent of visitors who feel the "magic", as opposed to, say, ten years ago. Is WDW being visited more because of its past reputation, while becoming more of a "been there, done that" experience? If the suits know what they are doing, they are having the marketing folks study that. My hope is that that is happening.
An article (actually a business article about the service industry) that I read recently posed the question, "How many people do you know that have visited WDW and come back not saying they had a great time". Well, recently, I know several of my acquaintances who have done just exactly that. And it scares me a bit.
Sorry for waxing so philosophical and getting a bit OT.
