I'm sorry, we have been to WDW so many times but I have never heard of PIN codes before I started reading this board. I can't figure out if it will apply to us or not. Our plan is to book a package once they come out on July 10 for a trip March 9-14, 2014. We are a family of 4 ("kids" 20 and 16). Should I call and ask about a PIN or will it not apply since March is a busy season for Disney. Thanks so much!!
