On our honeymoon in costa rica we splurged for 3 nights and stayed at a nice resort (the rest of the trip in cheapo hotels). The minifridge was free (soda, water, beer, candybars, snacks), refilled each night. I think I asked 3 different employees to verify before partaking, and even then checked the bill at checkout, and the cc after we arrived home. Mainly out of fears of other hotels that have "$20 a beer, $90 for the 1/5 bottle of liquor".
