I am a graduate of the College of Disney Knowledge -
- and certified Disney travel planner! My take on the meal plan - which I did one time just so I could speak from experience - is that it would be great if you had teens who could eat all that food. For us, it was too much. We like a light breakfast, big lunch, and then dinner on the fly. Eating your big meal at lunch saves you money - and breakfast in the room gets you out earlier (although since you are staying at the Contemporary, there will be no avoiding Chef Mickey's. If you don' have reservations there yet, I'd suggest you get them ASAP. Maybe for your first night dinner?)
Back to the dining plan - Yes, they push it pretty hard - but just say no would be my advice. Let me know if you have any other questions.
