You need to be a bit careful with the minibar as sometimes they may be turned off when you are not in the room. When we went to S'pore, we bought milk and put it in the fridge so that we wouldn't have to order from room service just to get a glass of milk for our son. When we got back the first day, we found out the fridge as well as all the lights in the room turn off when you take your card key out of the slot by the door as all the ice that we had left in the fridge had melted and the milk was warm. So next time we left the card key in the slot with a note to housekeeping to leave the key in, but they took it out any way!
