This was GREAT!!! I think it's an underutilized tour and probably one of the only ones with some really interesting, always-chainging information.
We toured the Animal Kingdom and got an inside look at the themeing choices, why they chose to use hidden barriers instead of "cages," etc... . Then we had the opportunity to visit the animal houses, see an elephant get his bath, pet a white rhino!!!; it was really a fun and interesting day (and I'm jaded and sarcastic, so you know I mean it!).
I highly recommend this. Try to go during a slow season so you have fewer guests in your tour and can get more one on one time with the guide.
