Last year my mom found rooms at the WL for $200 a night on one of those sites (I think Priceline). So yes, they are available, and the discounts are pretty good (especially since we got a free upgrade to club level!). I don't know how often and how good the discounts typically are. We paid for a standard room, and while I don't know how much it would have cost at the time, the same room a year later is $310 a night, so assuming it hasn't been raised a whole lot, that's a decent discount right there.
