The dining plan is only a great perk if you're not entitled to any other discounts. DVC members get a good discount of the annual pass, which also entitles them to buy a disney dining experience card. That card gives 20% discount at most sit down restaurants. I have tried it both ways, and we came out best off using the dining experience card. And we do tend to eat the most expensive things off the menu. But, the dining plan could still work out ok if you're not entitled to the dining experience card.
