I just got off the phone with CRO making ressie for our March vacation. Very,very nice CM. She even checked my name against any possible pin codes for those dates without me asking her to do so! Anyway she did tell me that Disney plays the number game to determine when to send out those rare pin codes. If advanced reservations are looking below expectations then they send them out in a flurry. She also felt positive about additional discounts and pin codes even for March due to Easter not being till mid April. So for all of us March 2006 folks lets keep our fingers crossed.
