Animal Kingdom Lodge (AKL) is really 2 separate large buildings. The main building is called Jambo House. If you are staying at the hotel, this is where you normally stay. Jambo House has 2 floors devoted to Disney Vacation Club (DVC), which also occupies the entire second building, Kidani Village. Collectively, the DVC rooms are known at Animal Kingdom Villas (AKV). I'll assume you're staying in Jambo House as a cash customer (vs. DVC member).
AKL is located on the southwest corner of WDW. To reach it, you need to drive past Disney's Animal Kingdom (DAK). There will be a guard at the entrance to AKL who will direct you where to go to check-in.
The main lobby is a lot like the Wildness Lodge. It's a long, tall, grand lobby with exotic African art in the middle. Check-in is on the left-hand side of the lobby. They will provide directions to your room. The restaurants, food court, and pool are on the first floor (I believe the lobby is either on the second or third floor) and can be reached by elevators on the ride-hand side of the main lobby. (There also are stairs near the elevators.) The layout is rather confusing for someone who has never been there and takes some getting used to.
There are several areas from which to view the animals. One is at the far end of the lobby, opposite from the entrance. Another is by the pool.
