Yeah, it's confusing. There are two buildings at the Animal Kingdom resort: Jambo House and Kidani Village. Jambo House is an alternate name for the main, original Animal Kingdom Lodge building, and it has a mix of regular resort rooms and Disney Vacation Club villas. Kidani Village is a newer building that consists entirely of Disney Vacation Club villas.
Kidani has studios, one, two and three bedroom villas. There's a pool complex, including a pool bar, and a table service restaurant called Sanaa.
Jambo has regular resort rooms, bunk bed rooms, and club level rooms, as well as some suites. There are also some studios, one and two bedroom villas. Most of AKL/AKV's restaurants and the gift shop are located here. There is a pool complex.
AKL/AKV guests can use either pool, and there are shuttles between the two buildings, or you can walk between them. Both buildings are surrounded by savannas.
If you book a regular hotel room, you will be in Jambo House. If you book a DVC villa, you'll have to choose which building you want to stay in at the time of booking.
