I'm the one who keeps posting sadly about my PIN not coming yet. Well, it came today (right before noon). I just called and we saved more than $1,600 off our 8-night split stay at the Poly and AKL in December.
THANK YOU TO THIS BOARD! I just visited for the first time last week, followed the instructions as described by several, and it saved me $1,600 and only cost me several hours and a lot of angst.
The fine print -- I created a new profile on the Disney website for my husband in his name, did the itinerary trick as described, and left it alone for a few days. It took about 5 days for it to arrive. I have also tried it with two other profiles in my name (2 different email addresses) and NADA. I hope this helps someone else! Be patient, it took several days for me.
