I don't think so-when I bought all 24 for a reservation I was making they stressed that I would not be able to buy any additional points until 2016 use year-guess you could call and try but I wouldn't think chances are good-they'd rather you book a cash room as they make more money that way
yeah i didnt think so but it never hurts to ask. I think they cap it at 24 becasue the minimum for an add on is 25 and they would rather have you purchase the points at $155 ratehr than $15
