Hi! I don't know how far you want to go down the rabbit hole with dining plan calculations, but there's a blog I visit that has done the math, and concludes that a TS "credit" is worth about $59, a CS "credit" is worth about $23, and a snack "credit" is worth about $6. (This only adds up to $88, with the remainder of the DDP's $94 cost representing the per diem value of the refillable mug).
