At the other DVC resorts, you get a 4 cup coffee maker in the studios, so I am guessing that it's the same at SSR. You get a 12 cup coffee maker in the one and two bedroom villas, so I would think that you could call Housekeeping and request a larger coffee maker.
We have mostly stayed in studios and have gotten both large and small coffee makers. And any specific resort doesn't seem to be part of that pattern. I wonder if people ask for a large one at some point and it just ends up staying there.
