We have the 3-bedroom Grand Villa booked for Nov 2016. We aren't DVC members nor did we buy points and actually bought it directly through the website. But, we had to book it in Aug 2015. Unless the Grand Villa is not what others are considering villas being available online? Not trying to be smart about it, just that we did book it online so as far as we've experienced it is possible. I think it's just a matter of the small number of villas actually available and how many need to be held back for actual DVC owners. Even booking 15 months out we still only got the only room available at that time so really the only advice I can give knowing it can be done in my experience is that you almost have to book them at least a year in advance.
