When I looked to book the same thing for March 2013 at the seven month mark there was absolutely no problem. All choices were available. I believe there are more villas open now so that would help even more
We are going the middle of March this year and had no problems booking at the 7 month window. We are in a studio, but the availability seemed pretty open at booking and I think there will be a lot more available next spring, because all the wings should be open then.
We booked for the week starting March 29th at the 7 month mark. We booked Garden view. Standard view was already full, and ocean view wall also not available. The difference between our experience and others in booking may be because this is also Easter weekend this year.
