I prefer SSR, but I am so in the minority on that one. I've stayed at AKL twice, once with a pool view and once on the Savannah. I'm not sure how many times I've stayed at SSR, somewhere upwards of 5 times.
The main negative with SSR is that it is a big resort. You can also see hotel row from some areas of the resort. These things is do not bother me in the least. I've stayed in the Paddock, Grandstand, Springs, and Congress Park. I wasn't a fan of the Grandstand section. Congress Park and the Springs are my favorites. The Paddock section was fine too, and we were right next to where they were building the Carousel section at the time, and I was able to walk to the main building within about 5 minutes. Both the Paddock pool and the main pool are very nice. Congress Park is a bit further from those pools, but it does have a quiet pool with great views of Disney Springs, it also provides the shortest walk to Disney Springs. I like the theme of the resort and find it very relaxing and enjoy strolling around it. I also have had good experiences at the Turf Club and Artist Palette.
AKL is a nice hotel. My biggest issue with it, is the hallways are crazy long. If I have to take a long walk, I'd rather be outside instead of a dark hallway. Housekeeping also left a lot to be desired. The main pool at Jambo was pretty busy, and just isn't that interesting to me. I do like the Mara and Jiko. We were not impressed by Boma. It's not ideal that you have to bus everywhere, especially since you plan to visit Disney Springs. We didn't swim at Kindani, but we did walk over one night. The water feature area does look like a lot of fun. I can understand why people love it there, I'm just not one of them, and AK is my favorite park.
