We have just purchased less than a month ago 160 pts. at SSR and for future reference I am trying to understand how add on points work when they are probably different use year and may be at a different resort. If you get 50 or 100 add on, could someone explain to me regarding the booking with different points and different use years or maybe the same use year. It would be nice to add on a little at a time but I want to understand that first.
