I second Sleepydog above. Jambo is the main building, but Kidani holds its own in every respect. I love both buildings. I own
DVC contracts at both buildings. Not that the different buildings for contracts makes any difference at all. Jambo has two nice restaurants and the morning quick service restaurant. Kidani has an excellent restaurant in Sanna and sometimes you could even get some breakfast things in there. They both have nice pools, they both have their own small advantages. You will be happy at either. And there is a shuttle that runs back-and-forth between both buildings about every 10 minutes. You just walk out the front door Tto get on it And you will be at the next building in just a couple of minutes. The biggest advantage is that they are both Animal Kingdom Villas, and they are both done very well.
Other relatively minor points. Jambo has a bigger lobby which is pretty incredible. One of the great lobbies of the world. Kidani has the largest collection of African folk art in the world, scattered throughout it. The restaurants Jambo has are good but having the quick service restaurant in the building is a nice advantage whereas Kidani doesn’t have that. Though,as I said, sometimes you can eat breakfast at Sanaa. The DVC rooms at Jambo tend to be slightly smaller and they are all two bedroom lock off as far as I know. Kidani has dedicated two bedrooms as well as Lock offs. Sanaa in Kidani is one of my favorite restaurants at Disney World. Kidani does not have a quick service restaurant but the trip to Jambo is very quick, and Kidani also has the advantage that the buses to the parks stop at that building, before going on to Jambo, so you are more likely to have plenty of space on the bus. Both buildings are large, but Kidani is incredibly large, and long, from one end to the other. Request a room near the Pumba elevator (I believe that is the one) to be reasonably close to the lobby, and to the underground parking, and the walkway to Jambo, if you decide to walk. (About a quarter mile walk, from building to building.) All of the DVC villas at Jambo are on the fifth floor. Whereas at Kidani they are on all the floors, so you can request a higher floor or a lower floor at Kidani. Finally, because Kidani is so much larger, and is ALL DVC, it has many many more rooms and much better availability than Jambo. I will take either building at any time. I do recommend getting the Savannah view, because it is so special. As far as I know, there is not a single other resort or hotel in the United States where you can sit out on your balcony and watch ‘wild’ African animals meander around, here and there.
It seems that the DVC member preference is for Jambo and I just want to make sure I’m not missing some major factor if I book Kidani, one day. My kids want to see animals from their room and both offer savanna views so without the help of you lovely people, I’d just go with whatever had availability. 
This is why I love the Dis! I appreciate everyone’s insight! 
with JH. Thanks for the insight!
