Yes, Realityland is not for those who want the pixie dust secrets! I was a business major in college, so the business side really facinates me. So often the business motto is cheap, fast, or right - pick two. But that is not really how Disney operates. Yes, there are times when creativity may be sacrificed for $, but it was really interesting to find out what wasn't sacrificed. For example, many argued that the castle should be visible from the interstate - draw people in. Ultimately, it was hidden way back on the property costing MILLIONS more in (60's dollars) because infrastructure had to be built first. The result was that magical moment when you see it for the first time. Creativity won!
I would try Hidden Secrets - even if there are inaccuracies - it is a great tour companion that will point out small magical things you would other wise never look for or see. I kind of like the idea of appreciating all of the extras the imagineers did. Everyone should have their work appreciated!
