We have a December UY, and once you get used to it, it's not so bad. Unless you go in December, just think of your points as being in the next year. So your 2015 points are actually good in 2016. Your 2016 points in 2017, and so on. As supersnoop points out, if you borrow 2016 points into your 2015 UY and then cancel, they would need to be used by November 30th, 2016. And remember, you can't just start your reservation on November 30th, the whole amount has to be used up by the date of November 30th.
