We're in a rough spot. Our children will be 6, 10 and 12. The oldest two will be considered adults at any buffet/character meals, yet they don't eat as much as an adult (the 12 year old is just starting to order some smaller meals off adult menus, but not at every restaurant). Now matter how I figure it, we'd have to do a character meal every day in order to save money, and that's not what we want. Also, although we love to eat out, we don't normally order an appetizer and a dessert at every meal, and certainly not one for each person in the family! We'd be more likely to get 1 appetizer and 2 desserts and share (and never both in the same meal!). With the meal plan, we'd be allowed 4 adult appetizers and desserts. I just can't imagine the amount of food we'd waste. And yet, I'd feel bad if I didn't use those features.
Before I knew about the dining plan, our original thought was that we'd do mostly CS meals this trip. That's still how I'm leaning, but the opportunity to have a nice meal everyday is soooooo tempting....
