It is not currently offered - and your guess is as good as anyone if they will offer it.
For us 2 adults 2 teens for 3 nights AKL savana bunk beds with dining the 40% off is about $47 cheaper than free dining would be. So I think it makes a big difference how many people are in your partry and what resort/room type you are booking but the 40% off can be a better deal.
