I agree that those "cold boxes" are pretty much useless. There are no controls that I could see, and it really didn't seem like there was any cooling going on in there at all. They seem like they were designed to be like a mini bar that you might find in a hotel room. There is an outer door with narrow shelves on it, and then the door to the cold area itself. The strange thing is, I cannot conceive of why anyone would have thought that a mini bar would be a good thing on a cruise ship. Does anyone know whether these things were designed to be mini bars, or ever used for that purpose?
