We only have used the studios and stayed at OKW only once. At OKW there were ice cube trays in the freezer which we used to make ice. We never did see any ice machines there. AT BWV there are ice machines on each floor. We usually fill up the bucket then stick it in the fridge on the shelf. It usually stays solid till it is gone, even for 2-3 days. I have never seen ice cube trays at BWV and all trips we have stayed there the freezer part could use a defrosting. AT OKW the freezer was not iced up.
OKW has ice makers in the refridgerator of all 1,2,and 3 bedroom units and ice trays in the studio. There are also ice machines at each bus stop and I seem to remember one of the pool areas having one, but I could be wrong about that. We have never needed more than the ice maker in the unit can make.
I was surprised when we stayed at BW (1 bedroom)in December that there was no icemaker like OKW. There was an ice machine near our room. I found out later that we should have had ice trays in the freezer (I mentioned it to the BW Manager after the DVC meeting).
