Rafiki is so boring. I've gone back there three times, but primarily to ride the train and look at that backstage cage area you all (you all is "younse" in pittsburghese for any outsiders) have been talking about. What a waste for such a large section of the park.
Not only a waste, but it makes it seem very sterile and not very 'Disney'.
I get that at night the animals need somewhere secure to stay, all Zoos have spaces like this. My wife and I were surprised that it was on full view on the train ride.
