You will know when you book which building you are in. If you have a preference, let them know when you call. Two of the room categories only exist in Jambo House. Those are Value and Concierge Level.
You will also check-in at the building you are staying in.
MS usually will tell you which one is available. If you have a preference, just ask. We have always loved our savannah view rooms at AKV. First stay was at Jambo, & the 2nd at Kidani. Actually think I loved our view better at Jambo. We were right in front of the giraffe feeding area. The kids loved it.
