The 2BR villas at Kidani have 3 full bathrooms, whereas they only have two at Jambo. With 5 adults, I would imagine 3 full baths would be desirable. The lock-offs at Kidani are a 1BR connected to a studio. There is a door from the hall into each with a door between them to connect the two villas. With that, the studio portion has a kitchenette and the sleeping area is a queen bed and sleeper sofa. The dedicated 2BR has 2 queen beds in the second bedroom.
Personally, for a 2BR we prefer the Kidani dedicated. A lock-off may be advantageous if the persons using BR-2 would prefer to have more privacy and a separate entrance. The 2BR villas at Kidani are noticeably larger. All of the 2BRs are lock-offs at Jambo. We don't like the layout of the kitchen at Jambo and the living area is narrow. Also, the savanna views at Kidani are superior, IMHO.
