I really had to 'work' for my AP to PAP upgrade at the end of Jan. I had purchased an AP voucher for my Dec trip, just before DVC announced the discounts. I put a call through to my DVC guide and asked him if there was any way that I could upgrade my AP to PAP and get the PAP discount. He said that he didn't see why not, but referred me to ticket services for a more definite answer. I called 'ticket services' (sorry, don't remember what # I called, I think it was a general # and I asked for them) and was told that "yes", I could - and further told that I could still get the upgrade even if I had already activated the AP - which I then did in Dec., planning on upgrading in Jan. First night in Jan trip is MGM EMH - at the end of the evening, DH and I decide to stop at Guest Services while we wait for DS and do the upgrade. I talk to several CMs (a supervisor is also called over) and am told emphatically that this cannot be done unless I want to pay almost $200. difference. I decide to check with someone else.
Next morning, I stop at Gst Serv at Int'l Gateway on way to Segway Tour - CM not only tells me 'no way', but comments, "I see that this has been explained in full to you once already!" Yikes ! big brother was watching me and I was upset that they were making me feel like I was trying to do something wrong !! I put a call through to my guide (knew it wasn't his problem, was just looking for advice) - he is the BEST and called me back at lunch time with the name & # of a supervisor at Guest Services at MK that he has spoken with that would help me. I call her and she assures me that I can upgrade with the DVC discount and that she has attached the info onto my name in the system. OK, I think I'm set

- head back over to MGM that night and go to Gst Serv - what do you think ??!!! Yep, told again that it cannot be done - I stood my ground and insisted that the CM (who was trying his best to be helpful) contact the supervisor at MK GS - well, after another 20 - 30 minutes of phone calls and supervisor coming and going, he got it to go through - and paid me $5.00 ! My DH even said "Wow, was it worth all of that hassle?!" But I have another trip with the family in October and will definitely be going to PI and the water parks- besides, I get really stubborn when I've already been told something and know (thanks to the DIS) that others have already done it, too ! So this seems to me to be another instance of "it depends on who you talk to" as to what info you get at WDW - wish there was an easier way!
