There is a bathroom in Animal Kingdom near the exit to Kali River Rapids that most people know about, however, very near that one (at the back of the Yak and Yeti building) is another bathroom that is always pretty empty. It's right around the corner from the little counter snack stand that is off to the side & around the corner from Yak and Yeti. (Did that make sense?

) It's fairly small (only about 4-5 stalls,) but much less busy, and much
drier than the one at the Kali exit. It's so secret it's not even on the CassWorld website referenced earlier
