We stayed on Zebra trail twice...once close to the lobby (just beyond the elevator) and this over looked the Sav above the pool on the map. The map I have access to right now doesn't have it labeled. We were by the watering hole. The other time we were almost the last room down the hall. We loved our room way down the hallway. This was over looking the Sav with Arusha Rock in it (the middle one) right by a watering hole again. There were more animals down here than on this sav closer to the lobby or so it seemed when we were there and a lot less hallway noise. I didn't think it was that far of a walk, but that's every one's opinion on that one. Some people have feet issues, small children, etc. We also didn't come back and forth to the resort either. DD and I left in the morning stayed out all day and came back. I'm always so blasted happy when I'm there that nothing seems to bother me either. We were most concerned about bunk beds and non-smoking so I didn't request a view. 3rd floor is the floor with the lobby too.
I guess I would recommend putting your requests in order through CRO and if you get to your room and you don't like the view, ask nicely to move.
