So now the question is how many points to actually buy... Historically, we go to wdw very other year at Christmas. I'm thinking nice we own dvc I'm going to want to increase the frequency, but I don't want to get carried away with a point purchase at we don't need. So, given our situation, I was thinking if buying about 1/2 the points we would need for a visit and then either borrowing or banking to use 2 years worth of points for our trips. If I want to upgrade to a larger unit one year or have a longer stay that requires more points, is it possible to "rent" points to make up the difference? If so how does that work? Thanks!
