I think I spend close to $10 washing & drying one load at CR. The machines are typical hotel machines. (I have done laundry in tons of hotel's and the dryers all suck.)
I'd recommend just washing what you need to get you through your stay. Keep it as light as possible. If you can, split your wash between 2 dryers.
Also, both the north and south wings have laundry rooms, the tower does not. In the North, it was up on the 3rd floor, very far from the pool. But there is a TV.
During our stay at WL, I did our load around 6 am. I was the only one till around 7. When I left at just before 8, the room was very busy.
