If I remember correctly the last couple years the free dining promotion came out in April. I may be wrong though. We went on the free dining in 2006 and hoping for it again in 2008. I think it had to be booked by the end of June.
So here's keeping our fingers crossed for free dining Sept 2008
Thanks Disney dreamin-gang, I'll be on the look out from April on! My AAA travel agent is really on top of everything, but I am too excited! Thanks for answering.
