So I just joined DVC....I have 150 points from 2015 and 2016 that I can currently use. I understand that. Where I get confused in on a future trip we want to book...for Dec 2017. I know I can book it 7 months out for the location I want..that would be May 2017. So I can use Sept 2016 points and Sept 2017. However, does this mean that I cannot use Sept 2018 points? Would I need to wait until Sept 2017 to book using those points?
