Believe it or not, I've started doing an update of these sheets - expanding to include all one-bedroom units. I think I may have bitten off more than I can chew. I have to tell you I am not being quite as meticulous as the first time, just going on every 2 weeks rather than the original pass I was looking it over at least 2 times for every 1/2 month period.
Honestly so far I am not finding a LOT difference from 3 years ago, though I will say that the biggest differences are (a) room categories disappearing faster at 7 months and (b) September appears to be much more popular than 3 years ago - which you can probably thank Food and Wine for that.
Also, so far as expected - SSR Preferred is slightly easier to get that Standard, but both are still pretty easy to get. If you want a last minute reservation, 1-bedroom preferred rooms seem almost always available.
And the Poly seems generally pretty available right up to 7 months, but gets snatched up VERY quickly at 7 months. New Tables coming in only 11 months! (I'm also including studios at Aulani for somewhat selfish reasons.)
