Kidani: We've had the pleasure to stay at Kidani many times as older adult "children" with our parents and loved the size of the villas, the decor, and the ability to see so much out of windows/balconies. It's such a beautiful resort. We also, personally LOVE Sanaa. Because we normally vacation around the Christmas holiday, we haven't used the Kidani pool so no comment there. I have never felt "left out" or "forgotten" at the resort. I love the intimate lobby and feel like the CMs here are passionate about their resort. I've also found some of the BEST character interaction here at this resort. Fond memories of walking up the staircase from Sanaa from dinner and encountering Stitch. And most recently we were checking in to Kidani and came across Mickey in Christmas attire that evening. (Mickey alternated with other Christmas-attired characters throughout our stay.) In fact, I have found the most surprise character interaction here with relatively short lines (compared to the other deluxe resorts where people can more easily spot the characters in the atrium). The other huge pro of Kidani as everyone mentioned above is the parking. I LOVE the covered parking. As far as I recall (and I haven't been to RIV yet), it's the only deluxe resort to offer this amenity. Granted, this is just a pro if you have a car on your vaca. I also love how both AKL buildings (Jambo & Kidani) share buses with no other stops. It reduces the travel time and helps balance out the fact that the resorts are further from the parks. I've timed buses before while at other resorts and the multiple stops at YC/BC/Swan/Dolphin or throughout SSR really adds up (especially when there are wheelchairs).
I will say that the cons are: 1) distance to Jambo (although you can catch the shuttle that goes back & forth, ride any of the buses going in the right direction - can't remember off the top of my head, or walk off those Disney calories); and 2) the long, long hallways (you can always request to be close to the lobby or close to the elevators).
Jambo: Love Jambo and just wanted to call out that, should you ever wish to splurge, the concierge lounge access is just truly special. (Granted, I've only experienced this pre-COVID-19 and have no idea the direction concierge lounges in the future are going.) Obv a significant point splurge, but a huge pro for AK home resort owners due to the booking window. We've stayed concierge only twice, both on points: once before AK was a
DVC resort (so it was part of the Concierge Collection) & we were on a separate floor (not the 6th) and a second time right after AK Jambo joined the DVC family (but Kidani was not yet built) so we were on the 6th floor. I don't even know how feasible it is for non-home-resort owners to get concierge villas anymore. Whenever we've stayed at Jambo, concierge or not, we've never regretted not having a car.
