I just had this convo with MS the other day, because we can add the dining plan independently and if we add the parks to that we have to pay for our 3 yr old. Originally just my wife and I wanted the dining plan and leave our 3 yr old off it, because she nor her younger sister eat that much, but, as they made very clear all people in your traveling party 3 and older must have the same options across the board. Yeah I was a little disappointed, but understand why they do it.
