I currently have 8 points in use year 2016 and 63 points in use year 2017. If I wanted to book a vacation at my 7 month mark {January 2017 for August} am I able to borrow from use year 2018 if my use year doesn't start until April?? I am thinking no but hoping yes. I am thinking my only options would be to risk waiting until April or buying one time use points. Also am I able to use the 71 in January and then hope for the best for the remainder of my stay? Thanks for any help
