VWL has one "public" laundry room, to my knowledge. It is on the first floor, behind the elevators. Basically, the perimeter hallway on the "Lodge" side of VWL. It has a few machines..which look like you need coins but you don't. Free of charge to VWL guests.
They have two washers and four dryers. It is located to the left of the elevators. Not to far down the hall on the right hand side. The first door is where the ice machine is and when you go through the next door you will be in the laundry room.
