I don't have DVC points anymore (hoping to buy some again someday). But, we always stay onsite. If we get APs, we will be back this year and will keep renewing our AP and coming back more. Without APs, we won't come back for another year or two. So, we would be spending significantly less money at the parks. I'm sure others can relate to that too. Either way it equates to less money in the park.
But, I read somewhere that Chapek is the one (or on the team) who came up with the Disney Vault. Put movies in the vault to create demand when they release LE copies of movies. I can't help but feel that's what he's doing with APs. He's creating a huge demand for them and he can absolutely charge more because he's created the illusion that they are a very limited commodity that can be taken away at any time.
But I'm still keeping my fingers crossed that we will be able to upgrade while we're there over the next 3 weeks.
