When calling to adjust my parents' reservation at WL with the up to 35% PIN they had received in the mail, I asked the CM to check if there was anything for me. I had the same PIN, as well as a free quick service dining PIN. My parents saved some money over the GP promotion they were already booked under, but we couldn't use our room PIN for our resort/room type. It was a reminder, though, that it never hurts to ask! I assume others have received and posted about these particular PINs semi-recently, but I guess I missed the news.
