I was really lucky to get the 30%/35%/40% PIN that runs through June 12th back in December. It was the first time we've gotten a PIN code!
Well, we booked our trip with our PIN but I was hoping to get the one that runs through the end of the year, because we've been considering a quick trip late this year as well.
On the advice of many here, I went to the Disney site and saved a couple of different vacation scenarios for later this year. I just went through the regular package booking part, not with a code or promotion, plugged in some dates, picked a resort and saved them. This was just a few days ago.
Well, today I got it! The 20%/30%/40% PIN for most of the year! Yay! The subject line of the email was "Explore your Disney resort picks, ***** Family!". Of course, the email was from Disney Destinations but I almost missed the code! It was on the bottom right of the email, which was mostly just about that particular vacation scenario I saved. So check your emails from Disney Destinations thoroughly! It looked completely different from the Alice in Wonderland PIN email.
Good luck to those still trying!
