we had a savannah view room and stayed in room 4425, which is on the 4th floor, Zebra Trail overlooking the Arusha Rock savannah. I am not sure about standard rooms but I can make a few observations/suggestions:
If you don't like walking or have small children, request close to the lobby. It can be quite a hike from the "outer" rooms
The lobby is located on the 3rd floor and the Zebra Trail is the same side as the food court, pool & arcade.
Wherever you stay you will LOVE this resort. My only downfall is that we did not have enough time to sit back and just enjoy the resort!!
