I did a tour of all things Gaudi while in Barcelona.
Pictures/Videos do no justice whatsoever.
This is not a picture of the Mona Lisa where there is only one way to see it and you will only ever gleam that same amount of information no matter how great the best camera in the world taking the photograph of it is. This is a lived in, three-dimensional space that you have to walk through to see certain things the way they were physically intended to be witnessed. For the Disney people designing a lived in, three-dimensional space that is going to be sought out by just as many -if not MORE- people, it makes perfect sense that they'd want to go and see and feel these places themselves.
This is one of the Disney expenses we should be applauding, not dismissing.
We wouldn't have gotten Animal Kingdom without trips like this - who knows what else.
