We had one in our room at WL last week. It was for the usual free dining (no room discount) and for the usual time frame of late August to early Oct (?) 2010. Sorry I didn't really read it that closely as we weren't interested.
We got free dining bounceback last year. We didn't get one delivered to our room, like some do. So, I called the bounceback number. Not sure what it is anymore....but some snooping around the DIS on another board, I'm sure someone would know it!
When we were there in August, we never got a flyer in our room. But like the previous post said, I took the number and code from the scanned post and called while I was there. No problem. Booked our Aug 2010 trip!!!
I was there in May 2008 for 3 days and got a 40% off flyer so we went again that September for a week. We were at the Poly the first time then went to the contemporary the second time.
