I roll all my points into the points credit pool every year, except those that I want to use for advanced reservation priority. And I avoid the end of the year "use it or lose it" problem, and I never have any left over, small number of, points to deal with
Exactly the way we handled ours for over 15 years. It always gave us a nice big pot of points to utilize & we never worried about expiration. It is a great feature and inexpensive (they'll probably change that soon).
