We stayed at SSR this last trip with our children, then 3, 7 and 9 yrs. I also had some of the same concerns about staying there, having had a really wonderful stay at the VWL which really felt very Disney. Turned out, we loved the resort and although the theming is subtle, it did not feel "un-disneylike". My kids also loved the pool area, moreso than the WL pool. My only complaint about the resort was that the bus service, but others seemed to have good luck with the buses, especially those that did not stay at the Springs (like we did) which was the last bus stop.
I wouldn't be worried about staying there ... you're on vacation in WDW and will love it. But if you are having any concerns, consider splitting your stay.
