There really is some mixed information in this thread. Animal Kingdom Lodge is the name of the entire resort. The resort has 2 sections, the original Jambo House and the newer Kidani Village. Together, they make up Animal Kingdom Lodge. Jambo House is a mixture of 'regular' hotel rooms and some DVC timeshare villas. It's also where the AKL Club Level is located, on the 6th floor of the main Jambo House building above the main lobby. There are a very limited number of DVC units located on the 6th floor, which members can reserve with points. There are also cash club level rooms available for non-timeshare guests. The Club lounge is the same for all. Kidani Village was built later and is made up of DVC timeshare villas, available for members to reserve - and I believe also some available for cash.
The original Jambo House hosts many of the amenities, including Boma, Jiko, The Mara (counter service), Victoria Falls bar, and Zawadi (an awesome gift shop where you can also purchase food/drink items). The lobby is also incredible. Kidani Village has a smaller lobby for guests checking in/out, and is home to the restaurant Sanaa. They also have a smaller store. Whether you stay at Jambo or Kidani, you're entitled to use the facilities on either side of the resort, including either pool. It's very walkable between Jambo and Kidani. Or, if you prefer, you can take a bus/van between. Animal Kingdom Lodge is much more spread out than CCV/BRV.
Both Jambo and Kidani have a large percentage of rooms overlooking the savanna, the home to many animals (giraffe, zebra, ostrich, antelope, etc). There are also rooms with a more standard view (pool, gardens, parking lot) - but if you stay in those rooms, there are still many observation areas around both sides of the resort to get close to the animals. Hope this helps some. I know I've repeated some things folks have already said, but I've also tried correcting some confusing information that's not correct.
