I haven't seen any the years I've been looking. But I did get good Black Friday deals on flights and hotel 2 years ago in advance of our DCL cruise out of Vancouver. I also find some good deals on Disney Gift Cards this time of year (often in December) that I've used to help pay for cruises or on board extras.
