To add to Michael's list, the master bath in the Kidani 1BR/2BR is private to the master BR. Those sleeping in the living area have their own bathroom. In Jambo, the bathroom is across a small hallway from the bedroom so that it is accessible to those sleeping in the living area. That means you cannot move between the master bedroom and bathroom in privacy. You will be in full view of anyone in the living area and possibly also the attached studio in those 2BRs that have the connecting door in the living area. Also, the Jambo master bath has a combined whirlpool tub/shower, Kidani has the usual separate whirlpool tub and free standing shower stall.
Regarding the savanna view, I prefer to be on the lowest floor possible. It puts you at eye level with the giraffes and you can see through the trees for better animal viewing. At Jambo, you will be on the 5th floor (or 6th floor if booking Club Level). That puts you at/above the tree tops and while you will have a more expansive view, some of that view will be of tree tops rather than of the animals that happen to be under those trees.
