Mad, for us it IS worth it. Like the other reply stated, it really comes down to how long you are there, plus how many are in your party, and if you eat in the sit down restaurants. It is good for character meals, and in most restaurants in Resorts, in addition to the sit down restaurants in the parks. If you kids are eating full meals, it may be worth it to you, too. We travel with 3 adults and 3 kids, so it does balance out for us.
