If you do not have a car or a kitchen and use everyhing it is worth it. We did the plan that was a meal, a snack and a counter meal. It was a lot of food for me. If you have a place with a kitchen and a car it may be cheaper to make food at the place and eat off property. And do a few places at Disney.
The biggest thing i would say if you are going and thinking about the plan is you should make table service reservations immediately. I would eat only where it costs one credit. Do not do any fancy dinners that cost two credits. Usually it's better to pay. But reservations open 180 days before. You can do those online. It can stink to plan so far in advance but it's better to have a reservation than not bc you don't want to be tired an walking around looking for food bc everthing has long lines or you can't get in.
