I feel like I must be doing something wrong. I get ~US$7200 whether I do a FD pkg at AoA or US$5400 to get the room deal and Canadian ticket deal. That leaves us US$1800 for nine days of food (really 8.5 days, 8 in the parks). $200/day for six people. My experience in December 2016 says that ain't much. I consider it a wash, at best, with me penny pinching if I were spending OOP instead of just relaxing, letting my kids order whatever they want and not having anxiety of over wasted food and wasted money when they don't eat enough.
Meanwhile. at Air Canada, I can get tickets, room, and dining plan PLUS air travel for CDN$10,500.
Do remember, it is best when discussing comparisons to list your group's make-up. FD tends to be dependent on group composition.
My family is three Disney adults and three kids. Nothing is beating Air Canada, and the number of tickets and number of meal plans is probably why our math is different than, say, a couple traveling alone.
