There is one every 3-4 floors- they are located around the corner from the elevator on the contemporary side of the resort(when you come in from the elevator you have to head toward the marina side of the building and they are on the same side of the hallway as the elevator). I think they may be on the 4th, 8th, and 12th but it could be the 3rd, 7th, and 10th. Ask which floors at the front desk as they are not labeled on the map.
