I have to admit, I can’t imagine what this thread is trying to ‘discover’.
Disney in general is kind of “known” for not having sales, not offering breaks, and everyone paying the same price (to a point). There are little tips here and there for how to save a few dollars (literally) or get a little extra something for your price... but, at the end of the day, the cost of a cruise is tied directly to the itinerary and the type of stateroom booked.
