Depends on what you want. If you want near bus stop, ask for it although that puts on south wing where all standard views overlook top of bus stop and road. Also request high floor which is wise for any standard view room to provide somewhat better view.
If you want shortest possible walk to pool ask for close to Rafiki elevator. That would put you on the north wing and exiting from Rafiki elevator on ground/first floor where parking lot is under the buidling, gives you the shortest possible walk to the pool. You could also just ask for close to or view of pool but distance to pool could be somewhat more. You should also ask for high floor.
If you do not mind walking a long way to lobby and bus stop, you could request to be close to where the standard view GV's are. Those standard GVs overlook Pembe Savanna and the standard rooms that are close to the GVs are ones converted to standard from savanna view and provide an OK but bot great savanna view.
