At 7 months out for February 2015, standard view was usually gone, and for time around Presidents Day weekend, Island Garden and pool view studios were also gone, but ocean view was available the entire month.
We are not Aulani owners, but go every year in January/Feb/March and have found that availability is not a problem if you book at the seven month window. Christmas/New Years is typically not available, but after about January 3rd it opens up. Book at the seven month window!
Our kids have the second week of Feb off every year. Since it is an inexpensive time to travel we usually take advantage of it. We are very interested in this as well because I'd like to plan a 2017 Aulani trip. This year I'll be watching that 7 month window very closely to see was is available and how many points I'll be spending.
