Yes, different animals - but my choice would be Sunset Savannah! Zebra, giraffe, antelope, ostrich........... lots of activity on Sunset!
(Kimmar, you will see that for yourself in a week! Lots has changed since you last stayed there! And I'm sure you will have a blast doing research for your thread!!

)
Pembe has the Red River Hogs and Okapi -- I do not recall what other animals, but it is the smaller of the 2 savannahs.
I have only stayed Kidani on Sunset Savannah, not Pembe. YMMV.
