There's only one change I would make to dgaston's post, Jambo House is busier. After staying at Kidani and coming back to Jambo House the noise and volume of people were very noticeable. But not as busy as it is at BWV.
If we were staying in anything other than a value or a studio, I would still stay at Kidani Village I really liked it, despite the long hallways. They only felt long after a day at the park.
We were just there in early June and we didn't find out until almost our last day, but there is a free shuttle van that runs every 10 minutes between Kidani Village and Jambo House. You pick it at the lobby entrance not at the bus stop. We usually walked the path between the two resorts, and I was always surprised how quick the walk was between the two, no more than 10 minutes between the lobby entrances and that included having kids walking with us.
In the afternoon the park buses might be full and you'll have to stand but then all of the Jambo House people returning from the park exit at their resort stop and then there are plenty of seats. So you end up standing for a only a few minutes.
