We plan to split most if not all of our CS meals with DD. If we throw away her CS credits at the end of the week it's not really a big deal. I don't think we have one single TS meal planned that will be less than $10.99 after tax and tip for her, so even the snack is a bonus. The CS credit is an added bonus. The way I see it, even if we order her a CS meal just for some grapes and a drink we've gotten our money's worth. If we don't use her CS meals at all we've still gotten our money's worth.
It's so much easier to see the DDP as a good value for a young child who 'throws away' all their CS credits than it is for a 10 year old who pays adult prices but eats like a child.
