If you want to spend the money, I would go for AKL/WL. We stayed in a Pool room at AKL and loved it, the view of the pool is georgeous and any room with a pool view will be a good location. I was afraid that we might miss out on the animal experience, but there are actually a number of viewing points that I loved to check out, so I was not dissappointed not having the Savannah outside my window.
Otherwise I think it really depends on what you want to do during your time at WDW. I would pick the resort closest to your favourite park.
