For which sized rooms? Any villa with a kitchen will have a full-sized refrigerator with a freezer.
In studios, it's hit or miss. The regrigerators are small under-counter units. The older refrigerators all had small freezer compartments in them. However, it appears that as Disney has been replacing broken refrigerators, the new ones do not have freezer compartments. Ours at SSR on our most recent stay, unfortunately, was one of ones that did not. For all of our previous trips to SSR, the studio refrigerator did have a freezer.
