You do not mention which view you have, standard or savanna. Any request related to either should be made through MS and not done online during check-in, for which requests are limited and some are ridiculous -- e.g., one request you can make when doing online check-in is for near an elevator but there are three elevators along each of the two wings, and that near elevator request can be met by putting you in any room in the building, so it accomplishes nothing. You should avoid asking for near the lobby, which is one of the requests that can be made with online check-in. If you can get near the lobby, you would be fine, but what has happened is that everyone in the world is now requesting near the lobby with the result that many do not get that request, and the failure to be able to give you your location request does not result in their trying to find something close to it, but instead results in their putting you in any open room location, which often means your near lobby request results in your being in the end rooms of either wing, as far from the lobby as you can possibly get.
Two good requests you can make with savanna view are near the Rafiki elevator (on the north wing) or near the Timon elevator (on the south wing), but both those requests need to be made through MS. The former would give you the shortest walk from the building, via down the Rafiki elevator to ground (parking lot) floor, to a gate for entry to the pool area, and put you within striking distance of the lobby and bus stop; the latter would put you close to the door on the second floor that is closest to the bus stop. Both those requests are also possible with standard view but are not necessarily the best standard views, e.g., near the Timon elevator leaves you staring at the back wall of the bus stop area. There are certain standard view rooms that are along the Pembe savanna that were converted from savanna view rooms. If you want a savanna view in a standard view room, you should request near the Pumba elevator (which is the last elevator on the north wing); however for that you need to be willing to do very long walks to the lobby and bus stop.
