Mine shows up on the AP website. Even tells me it's time to renew. When I click on the renew button, it takes me to the annual pass ticket selection window (i.e. shopping cart). The option to select the DVC Renewal ticket is listed as "This event is sold out" and not an available selection. It doesn't seem to recognize my ticket as a prior DVC pass.
Arrgh...the Disney website for AP has never been very robust technically.
That aside, if I renew (online or by phone) now does my 1 year start from expire date of the old pass, which is Janaury,or from when I first use it which maybe March or May? I presume it would be renewed in the form of a voucher until redemed later at WDW.
