DVC is indeed phasing out the mini-refrigerators with freezer sections. When I stayed at VGF when it first opened, I complained to DVC member services about the lack of the freezer section, as I take a lot of my own food due to religious dietary restrictions. Member services responded that "members have requested the units without freezer sections so as to make more room in the refrigerator"! They also stated that if I am in a resort with a kitchen, the kitchen would keep my food in their freezer. Not very convenient!
I have found, however, that if you turn the thermostat all the way down to coldest, items near the cooling coils will stay frozen. Next time I go, I am planning to try placing a rolled up newspaper in front of those items near the coils, so as to "block in" the cold, and see how that works.
