I called Disney Ticketing yesterday in an attempt to upgrade 2 three-day passes (that were unused due to covid shut down) into AP's. Waited on hold for 15 minutes then got a message saying "if you're a DVC member, press 1". I did. Got transferred to DVC. Waited on hold for 40 minutes.
Explained my request to upgrade 2 existing passes to the DVC cast member and she said "we can't do that today". I asked if Disney Ticketing could have done it and she said that Disney ticketing has asked that DVC handle all AP requests for any DVC members (to lighten Disney Ticketing's workload). I asked the DVC cast member why she "couldn't do it today" and she said that there are a small number of DVC staff that are handling ticket upgrade requests and that they aren't taking calls. She said that if I wanted to upgrade tickets that she had to fill out a call-back form and that I would have to wait up to 14 days to receive a call-back from one of their few folks that are processing such requests. I asked if I could get it done any quicker through Disney Ticketing and she said that once they found out I was a DVC member, they would just refer me back to DVC and I'd still have to get on the call-back list.
I advised that I'm going to be in Florida in 10 days and wanted to be able to make park reservations. I am staying off property. She stated that unless I could show a DVC reservation within the next 14 days, that there was nothing they would do to expedite the process. I asked what I could do if I don't receive a call-back prior to my travel to Florida and she said "buy the tickets from guest services" when you get to the park. When I brought up that that scenario would not allow me to make a park reservation until the day I arrived at guest services, she said "there's nothing I can do".
I don't think getting reservations, even day of, will likely be a problem. The totally insufficient staffing allocated to what is a totally predictable request (i.e. DVC members calling to upgrade passes) seems par for the course :-(
