I booked aulani at exactly 7 months for feb 2014 on presidents week.
Booked Sat-Sat 7 nights.
Standard and island view were already booked
Very limited pool view (dvc told me 4 studios available)
Ocean view had the most availability due to higher points.
Within 1-2 days after 7 months, days started becoming unavailable in all categories.
What made it especially popular was Valentines day was friday 2/14.... Making the first weekend of presidents week double as valentines 3 day weekend. Even still, by calling 9am at 7 months, i had no problem getting in.
Short answer, you should get in if flexible with room categories
Walk the reservation if you have the points to do so.
