A tad off topic, The other promotion offered at the same time as free dining is the room only discount of up to 30% between August 1 and November 5, 2016 . With a minimum of 1 night and a maximum of 14 nights.
I will say a prayer for your precious daughter. I hope your trip is absolutely perfect. May God bless her and your family, so you can take many trips together in the future!
I'm not confident on the dates I'm seeing, but it looks to be the "up to" 20, 25, 30% deal with obvious resorts excluded. Nothing shocking from what I see. Not 100% that it drops tomorrow, but that's usually been the game plan.
