Though you should have a decent chance, be aware there is a risk Jambo standard 2BRs could disappear before 7 months out (mainly as a result of studio reservations since all 2BRs at Jambo are lock-offs), lesser risk for the savanna view. At Kidani, both standard and savanna view should be open (and the 2BRs are larger and nicer rooms than those at Jambo).
If you are able to get standard view at Jambo, you should consider making a request for a room along Kudo Trail. More than half the standards at Jambo are rooms converted from savanna view and those converted rooms generally have decent views. All the standards on the Kudo Trail side of the building are converted rooms and thus best chance to get a standard room with a savanna view is requesting to be on that side of the building.
As to Kidani, you can potentially get a standard room with savanna view of Pembe savanna (the one without giraffes) by requesting a room near the Pumba elevator. However, getting that request would result in very long walks to lobby and bus station.
