I own at AKV & love staying at the resort, however, that sleeper sofa is horrible, much worse than the VGF sleeper sofa was before VGF got the Murphy sofa/beds. I’ve slept on the sleeper chair at AKV & found it to be far more comfortable than the sofa bed.
I assume AKV will get Murphy sofa/beds in the rumored 2025 refurb & will likely lose the spa tubs

You can use both Jambo & Kidani’s pools, I think Jambo’s slide is bigger.
Regarding savanna view, I’ll often opt to save points at Jambo by booking a standard view because many standard views at Jambo overlook a savanna & the others are above the pool, but that’s not the case at Kidani, IMO it’s definitely worth paying savanna view points when staying at Kidani, be sure to request a location that puts you overlooking the large Sunset savanna v. the small & narrow Pembe savanna when staying at Kidani.
A 2 br. standard view costs only a few points more than a 1 br. savanna view at AKV - if there’s a 2 br. standard view available at Jambo it might be worth it to spend a couple of points more to get the queen bed in the second bedroom. I’d request Kudu trail for location in Jambo standard since all of the standard views on Kudu trail overlook Sunset savanna.
