Not sure this has been mentioned before ... but I called in to have the free dining offer for my rebooking, as I cancelled our early April vacation. After a long wait, when I mentioned my new dates were early October, it was a no-go. They are only offering free dining for stays through September. I didn't try to push back as the CM would probably not be able to do anything, but they did say things could change and that I should check back in the future. I think that they should do better than offer the promotion to a four month period (Jun-Jul-Aug-Sep) ...
ETA: and they should probably put this on the website, defining the dates, so people do not wait over an hour on the phone (I wouldn't have called if that info was clear on the website)
