Thanks for all the people doing the maths. But I think it is more complicated than that. DVC is money upfront. One has to calculate net present value (those kind of Economy 100 math)to understand how much you are paying for each hotel night. What I am sure, though, is that Disney is putting this out for their benefit, not ours.
DVC and extra FP+ you ask?
Sure. Of course. Disney give these perks to people who are considering buying into DVC, not the ones who already bought it. How many of you have not seen those DVC booths in the park? The CM or the agent there often say you can attend a DVC talk and get extra FP+. For those who already bought DVC, Disney already got your money, they are less inclined to give you perks, you see. That is, unless you want to buy another DVC?!
The way it works for our family: we don't do DVC. If I want more FP+, and more fun at the parks, I spend an extra day or two at the park! That's when I give money to the mouse, not 20k up front!
