Hang in there... you'll probably have to remain very patient. I'm going January 7th thru 10th, and no Entertainment rates have been out yet. I do believe there are AAA discounts out for that time, and they just released the package where you pay less for staying four nights. (I'm unfortunately staying only three, so I can't take advantage of that.)
I'm leaving in just over 50 days, and I'm still waiting... I may not end up at that resort. I know everyone says it's worth it for the express pass, but you know... I'm just not so sure.
