We don't have any disney experts in this area, unfortunately. The last 2 years Visa has put out an at par for Canadians and for some reason I thought I remembered it being around the end of Oct. early November for travel in Jan-May. My TA said I could book our next year disney trip any time I wanted and I thought maybe around the fall to see if the at par did come out again. My TA thought that with the new MYW tickets we would likely never see another deal come out again, she was willing to bet money on that one and she said if I book something and they did happen to come out with that offer, I could NOT change what I have once I have started paying on it. I thought you could change things through disney at any time really?
