I requested zebra trail w/ bunk beds but forgot to add the Arusha savanah view. Well, I was on the opposite side of the hallway, so had Uzima savanah view. Well, we were still very pleased with our view, even though we could see the infamous people pens that I heard so much negative comments about. I learned one thing about AKL, and that is there is no such thing as a bad savanah view! No matter where you are at, you will see animals! I'm sure you will have a great time there.
If I could recommend one thing, it would be to request 2nd or 3rd floor. We had 3rd floor (the same floor as the lobby) and loved not having to use the elevator to get to our room, and were just one floor away from the restaurants and pool area.
Have a great trip!
As for the people pens, they are an area next to the resort that has bamboo type fencing. Not sure why they call them people pens, since I never saw any people.

The pens didn't bother us, since the animals really seemed to gravitate to the water hole right next to the pen.
O.k, so perfect request would be 3rd floor Arusha savanah on zebra trail, close to elevator.
Congrats on your wedding!
