Well, you go by it, if I recall correctly - definitely spend some time in Asia.
It's interesting, especially if you like to know how things are made. After the History Channel show a few years ago on how each park was built, I thought this tour would be enjoyable.
What made it especially so - and in fairness, this was about two years ago - was that of the fifteen or so Guests waiting to start the Animal Kingdom tours, I was the only one doing Wild By Design!!!! Yep, that's right - I accidentally had my very own personal tour guide!
