My family of four are going to WDW for the first time in a couple months. My brother brought up the question about how the meals are paid with our room key cards. In the mornings (or at any time of the day), can one person take all four key cards down to the food court and buy breakfast for the whole family? I read the part about how you can't use your dining credit for a non-DP guest, so I was wondering how they enforce it. Do they require each guest with a dining plan card to be present when ordering? Also, with the refillable mugs, can one person grab all four and fill them up with coffee in the morning? I know this is sort of a dumb question, but it would make our morning planning a lot easier. Thanks!
