This is probably old news...if it is please forgive me. I did a search and couldn't find it anywhere else. I just got off the phone with DVC and they told me that they just got the email this week that you can now buy park tickets and annual passes at the concierge desk of all the resorts. You can also trade in vouchers for tickets purchased online. The only thing you can't do is renew a pass. I had read on here several months back that you could do that at Animal Kingdom, but that it wasn't yet possible at other resorts. This week they apparently added all resorts! Makes my life a lot easier, I can just trade in all our AP vouchers at our hotel and skip the step of doing that at the parks.
