Me neither. I swear I get at least a dozen disney related emails each week from their various websites, etc. We live out of state, but have made 4 trips since purchasing Premium APs last Oct (one of which was a 3 night stay at the GCH). We bought MTOT Party tickets last year. We have got trip planning DVDs after requesting each WDW and DLR as our primary interest and we even got the
Disney Cruise DVD last week. Have been stopped by Guest Relations every single trip to do a survey or give an email address for a later survey and have completed those when the email came. Made purchases from DisneyStore.com and are members of the Movie Club and order frequently.
Still haven't ever received a PIN. I am not sure there is anything else I can be doing to try to draw their attention anymore, LOL
It really must also have a lot to do with luck (aka random computer processes and algorithms)...
