I went on the Magic your Way premium Plan in Dec. Both of the plans are all inclusive vacation packages that include three sit down meals per day (the premium also includes a snack), umlimited use of recreation, behind the scenes tours etc. I'm sure someone here has lots more info to give you on these plans. We loved the Premium Plan. That said, I don't think it would have been worth it for us to use mainly for the dining...we love to eat...but it was the unlimited golf, behind the scenes tours, etc...that made the package a good value for us. Hope this helps a little.
Before joining DVC, we also did the Platinum/Premium packages - for the golf, child care, tours, viewing spots, boats and other included goodies, not so much for the dining. I wouldn't do it just for the dining.
