Sure, but my theory is that partial VOI banking happens as late in the season as possible and I would bet banking is mostly done from VOI from the least desirable resorts (for the most part). For instance, I can't see a week 52 from WSJ pool villa or from 52 WKORV OF banked in full or partially (or any other high demand unit). Of course there are extreme situations, I am talking in generalities. But I bet it is usually left overs.
So, the way I see it, it is the worst evil in the system. This is perhaps my selfish opinion because I get a negligible benefit and get more competition that did not exist before.
I know some people bank their full units, and I guess that is fine because they want to go to a resort that takes more options than what they own in a year. So, that benefits them...it affects people who don't bank negatively when we don't click fast enough at 8 months. We are using my current year SOs and they are using their banked SOs. Shouldn't we have an edge?
