This may sound confusing but here it is: we have the dining plan for our DS who is 12 and our DD who is 9. Our 12 year old won't eat at any TS places so is it OK to use his for our DD if she doesn't like anything on the children's menu? This is the first time using the dining plan so I'm unsure on how it works. Also, can you use a snack credit for an order of french fries or get a double order of fries as a combo for a CS? Thanks for any input!
