I didn't see the 2011 information either. But if you look on the DVC members website under perks you can find the link for the 2010 marathon weekend. It contains a special link as opposed to a discount code. So I would guess they havent released the discounts for 2011 yet.
I emailed about discounts for cast members and was told there are no discounts for the Wine and Dine 1/2 or the 2011 1/2 or full. The only discount being offered is $5 off the ESPN 5K at the end of February.
