First, I freely admit that I am biased. I've stayed in three rooms at SSR. The first time, I got Congress Park because that's all there was, and I had a view of DD, and I fell in love. The next two times I requested Congress Park with DD view and was willing to wait until 4pm to get my room.
That said, when SSR was DI, I stayed in the building that would be what is today 4101-4436 with my mother (who doesn't want to walk much) and it was perfect. Close to a bus stop, close to the main action (spa, pool, gift shop, etc.)
