For whatever it is worth, I thought the booking online window was exactly what was discussed previously in this thread. But...
Last night I went in right after midnight and booked a reservation within my 7 month booking window and was successful. The interesting thing though is this actual resort is one of my home resorts. But I did not have enough points for this resort to book the room 11 months out. I had to take from other contracts from other resorts to make up the point difference and that is what made this reservation a 7 month booking window.
I found my success to be very interesting so I thought I would share...

Do you think this was an error? If so, SHHHH let's not tell anyone...
