To answer the OP...yes, all standards at Jambo are pool view.
To answer the above: Yes, you can make a request like that. MOST of the standard view rooms are along the back side of Giraffe trail, and about 1/2 the back side of Zebra trail.
Putting you "near" the elevator would put you either at the begining of Giraffe trail, or toward the middle of Zebra trail. Those, to me, would be the preferential areas to stay because you'll be closer to the rest of the amenities and the pool area.
