I'm not sure I agree with all of the issues about walking at Kidani.
I have stayed at Kidani, Jambo House, Sarasota Springs, Pop Century, Cabins at Fort Wilderness, Caribbean Beach, Port Orleans, and Grand Floridian. I have been to almost all other resorts as well.
Each one has their walking. I've not stayed or been in any resort where there wasn't some bit of walking to do. Walking to any pool, to any lobby, to the gift shop, counter service restaurant, etc.
Truth be told, I walked the most at SSR. I walked a lot at Pop Century. I walked the least at GF, but I still had to walk quite a bit to get to the different places at the resort.
If the parking is an issue, you can do valet, which isn't that much $$, and save yourself some walking.
There is always going to be a lot of walking at WDW. Whether at a water park, theme park, DTD, resort, or wherever.
I've stayed at Kidani four times now, and have stayed on the Pembe Savannah, which is farthest from the lobby, but still I have found it no farther than any other resort.
Maybe next time I'll hook a pedometer on my belt and measure it all out. My guess is that it all averages out to be about the same with very little difference between resorts.
I am glad to hear your view because I often wonder about this. We have stayed at POR, POFQ, CB, SSR, Kidani and VWL/BLT on our upcoming trip with the BWV booked for this winter. At SSR the laundry was so far from our room that I dreaded it. I am sure there are the few room right by everything but still.
We even found the bus rides to be shorter from Kidani because at POR there were so many bus stops but I have never timed it out.
