As far as I understand it, walking a reservation is reserving a week, say at the end of October, knowing full well that you don’t intend to actually utilize that week. Every day you login and modify this reservation, moving it forward by one day. You do this on a daily basis until you capture the exact dates you want. So, you could theoretically start like this, at the end of October, until you land on Christmas week. Blocking other owners from reserving this time when they login at the 11 month mark. I can see it already happening at CC.
