I assume you mean have
not had issues, and that is the gist of my trying to educate new/resale dvc buyers on points requirements. It is sad to hear someone say they thought they could book x room with their points, and it's never available - I show them there are 12 rooms they were trying for, but 80 rooms if they go one level of points up (and usually that adds a view or extra space)...
I almost got a Grand Calif this morning (had to cancel a trip to do it, ended up losing both my cancelled and hoped for reservation in the process). But I'm Studio and typically trying for holiday and good weather dates

Booking DVC could definitely be a full time job if you are skinny on points.
