The over analyzing financials of what is supposed to be a fun to use purchase was a bit much for me.
I looked and saw that I could basically spend on
DVC what I was paying to stay in a moderate (or heck less than one of those AOA family suites, and that was before they went up even more post skyliner!) and bump up to nice deluxe resorts. There is no "saving" with DVC really for us, we will end up spending more most likely vs not having it. The room is only a minor part of a WDW vacation when you are going to spend a lot on park tickets, food, merch, travel, etc as a part of it.
