I agree with the above posts..........cabins are indeed point purchasable.
HOWEVER, I stayed at the cabins 2x prior to purchasing
DVC and would never, ever use my points to stay there again. I do love FW and the cabins but I feel that I get more for my points by using them at a DVC locations: better locations, less points per night for similar accomodations, better pools, etc.
And you know how people complain about the SSR bus service??? It has nothing on FW! You actually have to wait for a bus to take you to the area where you wait for a bus! I felt like our group spent half of our days transporting around town.
