Another thing you should think about is that the resort is VERY large. Depending on where your room is, there could be a long hike to one or more of the amenities. Some people can't deal with the lack of a CS restaurant, and if you are staying in the part of the resort farthest from Jambo, it's a pretty good walk, 15 minutes or so. My room was really close, only 5 minutes, but we didn't need CS since we had enough food in the villa to feed an army!
The pool is on the opposite side of the resort from Jambo, so if being close to both was important you would need to make a decision. Also the bus service is just off the lobby (a little to the Jambo side), if you want to be close to that, you might request close to the lobby. If you purchase refillable mugs, you fill them in the gift store which is off the lobby and also where you check out DVDs to watch.
For us none of this was important since we had our own car. What was important to us was being near an elevator which they honored and put us right next to Zazu. This may not be as important, but the animals are a little territorial. Evidently the Ankole Cattle stay on one side of the savannah, and the Roan Antelope stay on the other. The Giraffes & Zebras get around, and the day we were leaving they introduced male vultures to the Sunset Savannah. It was quite amusing, they were surrounded by the storks who were eyeing them with sort of a "who are you and what are you doing sitting on OUR tree" look.
However it turns out, I'm sure you'll have a great time! It's a neat resort.
