This is an old plan that has gone away. It was called the Food N Fun Card then DDS. With several evolutions, it was a good plan early on then it went to H$ll.
The earliest version I remember was about $35-38 per day per adult and $13.50 per child. Initially you could eat at basically any restaurant for breakfast and dinner. One appetizer, one desert, one drink (non alcoholic) and an entree. I think there may have been a few restrictions as to certain things you couldn't order but only things like Lobster if I recall correctly. I don't remember what restaurants were restricted but there weren't many. They did not restrict the kids to children's meals, big mistake with my crew. I think the cutoff for the children's portion was higher than for the parks, either 11 or 12. The fun part initially included the fishing excursions, trail rides, water sprites and the like. Later they changed it to any of of the 3 meals, your choice of which 2. They they started whittling away at the activities and raising the price. First they took away the fishing excusions and replaced it with the parasailing, don't remember much after that. The program had to be for the entire party and for the entire length of stay if memory serves.
We used the program when it was in the above form but could be used for lunch and dinner. We did the fishing excusions twice, trail ride and ate ourselves silly. By the end of th 3 or 4 days, even my kids were saying "don't even ask us about desert". Our costs for when we used it were slightly less than $400, I kept track and the full cost would have been almost $1000. Had we been paying out of pocket, we wouldn't have done all the things or eaten everything so our actual costs would have been much less. I came home saying, this program will not last as is. Personally, it was crazy not to restrict the kids to kids meals plus only one of each included activity.
Later versions included a similar but different plan with coupons which did limit somewhat the number of activities. Another version even later gave you a gift card for $55 which you paid $50 for. Initially that had some activities with it as well but the last version had only the food which worked out to be at a 10% discount and you couldn't combine with other discounts. I had the Disney Dining experience card which gave me 20% off, easy choice, especially since the other program was use it or lose it..
