I am a BCV DVC owner but have stayed at SSR 5 times plus another stay at THV there.
While a studio with 4 people would never be my choice over a hotel room with 2 beds, I can give you a little info on SSR.
There are 5 sections, Grandstand, Carousel, Paddock, Congress Park and Springs. Those are the order of the bus stops. There are two themed pools in Springs and Paddock. There are counter service, mug refills in both those sections. There are quiet pools in both Grandstand and Congress Park. Only Carousel is without a pool. Therefore, Carousel is the least favored section.
I prefer Paddock over Springs because I dislike the Springs bus stop being last. Not only are the buses sometimes already full by the time they get to Springs, the Springs stop is more crowded from people who walked over there to use the store, etc and then hop on the bus from there.
Springs does have the restaurant, main counter service, store and boat dock to DTD. However, the walks from the other sections are maybe 5-7 minutes. Sidewalks and landscaping are nice throughout the resort.
Congress Park gets you the best views since many of the rooms have DTD views. It's a very short walk from Congress Springs to the Paddock pool and this is my ideal room location.
I have stayed in all sections except Carousel. The one time we were assigned a room in Carousel, I requested a change at checkin to any other location and it was granted-I was given a room in Paddock (it was my 2nd stay in Paddock).
