All the values resorts have what is referred to is a beverage cooler; they were completed with the installation in April 2012.
They are the size of a small dorm fridge.
The reason it was done is because it was cheaper to install them in all of the rooms, rather than pay for storage area for requests, the personnel needed to keep track and deliver/pick-up the fridges, lost time wages due to back injuries, etc.
They are also are small enough and have no freezer compartment, that they don't use up nearly the electricity that the fridges do in the moderates and deluxes. They basically just keep things cold.
