I booked with the 40% but did not receive a code. When I called and made the reservations, I asked them if they could apply code "ABC." The CM said he would see. He also checked several other codes to see if it would work to my advantage. The code worked and he did not ask for a pin. After seeing all of this on the DisBoard about needing a pin, I became concerned that I had done something intentionally wrong. So I called Disney back and explained to them that when I booked, I asked for code "ABC," which was applied, but then saw online that this was possibly a pin only code. She checked and said I did not have a pin associated with my name, that she did not know how the code went through without a pin. However, she spoke with a supervisor and since they made the offer, it stands as it. It would not be revoked or the rate changed. I explained to her that I just wanted to be on the up and up and if I was not entitled to the code, I understood. They were very polite and stated that once the offer was made they would not do that to me. I was even able to add more days on!!!!! If the offer was not going to be valid, I wanted to go ahead and find out about it now. When I called and made the reservations with the 3 letter code, there was not speculation at that time about a pin # being needed, so the reservations were not done with ill intentions or trying to pull something over. Hope this helps others.
