Lead request should be Sunset savanna view if you want to see giraffes and Zebras (Pembe savanna has neither). Second request should be either close to the Timon elevator if you want to be closest to bus depot on south wing, or close to Rafiki elevator if you want to have shortest possible trip to pool on north wing.
Note that simply requesting “close to elevator” is a useless request. There are three elevators spread out along each wing and every room in the building is close to an elevator. You need to name the particular elevator you want to be near for the request to mean anything. Also, requesting “close to lobby“ has a high level of disappointment because it is the usual request made by far too many guests, leading to many not getting it.
