Both GV's at AKV are good. The single story Jambo GV has the pool table room. a huge master bathroom with a tub that faces a TV, and very large balconies. The two-story Kidani GV has an extra bathroom, windows from floor to second floor ceiling in the living room for viewing, an alcove at the top of the stairs that provides a pull-out couch queen and TV, and the w/d is on the first floor where it should be (unlike some others like SSR and the two-stories at BWV where it is inconveniently stuck on the second floor), and if you want to save points, two standard GVs which actually have a savanna view (just more limited than the savanna view rooms).
Kidani has the much better two bedrooms that have three bathrooms and are about 100 sq ft larger than Jambo. Also, if you have a car you can park close to an elevator fairly near your room in the under-building parking lot (Jambo lot is across from the front entrance and walk to room can be not bad to forever from the parking lot..
If rooms mean significantly less to guests than amenities, then Jambo stands better with the larger lobby and store, larger pool (but Kidani has the excellent waterpark area for kids and a much longer pool slide), and multiple restaurants including a quick service.
