Sorry, but no. The small fridges are locked, at least ours was. You have to ask for a key. They have drinks and snacks in them that are not included in the all inclusive. You have to pay for each item. They are very expensive, too. If you take anything out to put your items in you will be charged for that item, whether you actually eat or drink or not.
I don't hink they will bring you up an empty fridge to store food in, but you could ask them. Pretty well all you can do is put a couple of bottles of water or beer in the ice bucket.
