When you call to reserve your 2 BR villa, add a request that you get a Kidani villa. This request should show up on your confirmation. I believe you have a very good chance at your request. Good luck!
Jambo House & Kidani Village are booking categories. When you call to reserve at AKV, you will have a choice (depending on availability) of either Jambo House or Kidani Village. You will know when the reservation is confirmed which location you are in and you will check-in at that location. If you have a preference, make sure you let the CM know.
There are a couple of room categories that only exist in Jambo House. Those are the Values and Concierge Level.
You book either Kidani or Jambo, so you know where you'll be. A benefit of Kidani is the 3rd bathroom in the villa. I like the ambiance of Jambo, so if I didn't need the extra bathroom, I would book Jambo.
Turns out it was a moot point, when i called back the next day to reserve, they didnt have one of the nights. As a matter of fact everywhere was booked except OKW and Sarasota Springs. So we opted for OKW (one of our favs anyway) and wait listed AKV and Bay Lake
