Savannah View is one of the jewels of Disney World. It also is a unique experience that is not available at any other hotel, anywhere in the world.
If you are in Kidani, which is a great place in its own right, and if you have a Savannah View room, then ask for a room near the lobby, or near the Timon elevator (it is the next elevator to the south of the lobby, and has good access to the parking garage and bus stops) and ask for a room on the Sunset Savannah. There are two Savannahs at Kidani. Sunset is by far the largest. But Pembe Savannah is to the far north end, and it IS NOT worth it, if you ask me. On the other hand, the OTHER SIDE of the far north end (or all the savannah views of the south end) looks out over the Sunset Savannah. Sunset Savannah is the biggest and very often has Giraffes and Zebras and various antelope-like species that you can see. DO NOT EXPECT THAT ANY OF THE SAVANNAH VIEWS ARE GOING TO LOOK LIKE THE NATURE FILMS WITH THOUSANDS OF ANIMALS MIGRATING. Even in Africa, those migrations only happen twice a year. The rest of the time, the animals are just scattered around the savannah. At Kidani, if you ask for a room on the 2nd or 3rd floor (the lowest floors available) you will be closer to the animals. But I have also had rooms on the 5th and 6th floors and was quite satisfied. If you are at Kidani in a Standard Room and want to try for a partial savannah view, ask for a room up in the north end, by the Pembe Savannah. It is past the pool and is quite a walk, but maybe worth it.
Jambo House looks out over the Sunset Savannah from the southeast side of the savannah. Ask for a room along the KUDU TRAIL, with a look out over the Sunset Savannah. The other savannahs at Jambo are the Arusha Savannah in the middle of the building (between the wings of the building). I don't know how that view is, since I have never had a room with that view. And the Uzima Savannah, which is a smaller Savannah to the east, more comparable to Pembe at Kidani. I don't necessarily recommend that one, either, but I don't know. All the
DVC rooms at Jambo are on the 5th floor, I believe. If you are at Jambo in a Standard Room and want a partial savannah view, ask for a room along the Kudu trail. It will give you a partial view of the Sunset Savannah.
