some tickets going up in the beginning of the year, and APs maybe going up in the fall. I could be wrong, but I remember kicking myself for not buying the tickets earlier for our fall trip, as they had gone up right before. Someone please correct me if I have it backwards....
Just wanted to mentipn that if you have a DC card or a Disney Visa, you would benefit by purchasing your tickets before Christmas. Disney Visa has triple points through 12/24, and DC gives about 15. off per AP till 12/31. Not sure about the discounts on other tickets.
