These shares were for the value resorts, and Disney eventually put fridges in all rooms, so the fridge swaps are no more.
However... there was a recent recall of many Disney resort fridges, so at the moment, its possible to get a room without a working fridge again. Check the Resorts board for your resort to see what theor status is... I believe the fridge replacements are expected to be completed soon though, so depending on when ur trip is, might be a non-issue.
