And you could also stop going to WDW.
For me, the big thing is, simply not knowing how many points we'll need as time goes on. There are too many variables:
-We could buy too many points and not need them as time goes on. We won't need as large a room as we need now, and we may not go for 2 weeks.
-We could buy too few points and not have enough for the next few years.
I will say this though, and take it for what's worth. Everyone I know on a personal level that has owned DVC, has sold it. Now granted, it's only a handful of people, but that speaks volumes to me.
