I spoke to TMs from both non-DVC & DVC & on the resort side (non-DVC), if you buy a "package" meaning room & park ticket directly from Disney, it has to be minimum of 4 days & can be longer to have the 2 free days added. From the DVC TM, only a 4 day ticket will be allowed to add 2 free days, which I explained sounded lame because DVC stays tend to be longer than 4 days. TM said he could connect me to ticketing to possibly get more answers, but the wait to connect to them would be over 45 minutes which I didn't have time for on that morning. Lots of uncertainty from what TMs are being told. A customer service TM told me that DVC would have to connect me to Ticket Services anyway, so I could call any ticket line & ask to be connected for the 2 day upgrade & Ticket Services would be able to check that I have a DVC stay booked to qualify. So I'll be up at 2am HST to call the WDW ticket line in the hopes I can get thru & wait to be transferred since they open 2 hours earlier than DVC. If they can't help me, I'll be up again at 4am HST to speak to DVC. Here's to hoping I qualify for the 2 day add on!
