Now to complicate - I've read stories and theories that you can buy a 6 day pass through the newsletter link to mousesavers, grab that discount and then upgrading the tickets to the DVC AP at the window to the park (but only do so after using the passes once & before all the days are used) - double discounts in theory... I'll admit I'm still skeptical and curious as to how that works, but if it does, you can save another $100 for a family of 4 by doing this. Worst case would be Disney says you can't upgrade to the AP at all. I don't see that happening as they make their money off of us being in the parks buying stuff we really don't need
& the more we're in there, the more we spend.
