Two very different resorts in so many ways. Kidani/AKL is a beautiful resort, but fairly isolated. Nothing is really walkable from the property. Also I don't love the layout of Kidani specifically. If you get stuck at the far end, it's a very long way to the lobby area.
SSR on the other hand is more low key laid back sprawling property (65 acres)--more like a vacation community. It's big selling point for us is the proximity to Disney Springs. Personally it's an easy SSR for on that one, as I'm just not a fan of Kidani AKL (and it's one of our three home resorts). I like to visit AKL occasionally, but not staying there. AKL wins on dining...but with Disney Springs next door to SSR...maybe not. Plus SSR has the spa if that is of interest to you.
