We sailed this past December on the Fantasy. It was the first week of December. We didn't book until the end of September but I started checking in July. There were multiple discounted sailings that came up in September. My DD is a crew member and were were holding on to see if anything was offered under the crew discount which is why we booked so late. There were several sailings that went to guaranteed status for inside/ocean/verandah. The first 2 weeks of November, the one we went on and 2 other sailings in December which were right around Christmas. I think important to remember on that though is that the Treasure started sailing at that time. In the end nothing came up under DD's discount so we booked full fare at $3800 for the two of us but shortly after we booked it went to guaranteed and was even lower. Then a couple weeks after we booked DD had discounts available and they kept coming right through the end of January which is very unusual.
