The PIN Code I received several weeks ago was good through 12/24 and we were able to apply it to our stay at the Poly on the nights of 12/23 and 12/24. We did have to upgrade from standard view to lagoon view which made the night of 12/25 more expensive, but even so it saved us $200 total. This doesn't help you if you didn't get that offer, obviously, but it is an indication that such offers are sometimes made.
