I had booked at POP (value) about 8 weeks ago. The week before last I received a 20/30/40 pin code, and was able to upgrade to a Deluxe. It still costs a little more, but the space and comfort at the end of a long Disney day was worth it to me. I'm not sure if you could "downgrade" and it also depends on room availability. I read a few other posters here trying to upgrade from value to mod or deluxe, but the rooms/resorts they wanted didn't have any availability for the discount rate.
