Just so you know, the view from the Concierge rooms is not the best. The pool view rooms are over the restaurants so if you look down you will see the restaurant roofs which extend out into your view quite a bit. The savanna view rooms face a little alcove of the Sunset Savanna so the view area is limited. In addition you are above the tree tops and they obscure part of the view.
We really enjoyed our concierge stay but I would advise keeping your expectations about your view pretty low so that you are not disappointed!
