So we are going in November with the dining promo, we are staying at the Yacht Club in a standard room, when I did the math we were saving over $500, and that is with the Park Hopper, so I am not sure where you came up with the numbers, and YES you could go to Target or any store and pick up food and drinks, keep them in the room, we did this our first time we ever went to Disney world, and yes it saved us money, but it definitely was not the same experience, if I was on an extreme budget and could barely afford to go, then I see where you are coming from with buying your own food ahead of time, but if you want the truly magical experience I don't think there is anything like it, it makes the trip like an all inclusive feel
