I dont know how big an eater your family is but since there is no diffrence between the QS child credit and the QS adult we always get an Adult QS meal for breakfast as you get 2 drinks at Breakfast at the resort or a drink and side and we Split the meal! we have 3 boys that we always split their QS lunch and breakfasts by always getting the adult meals,We even do this for ourselves as we find that eating a QS breakfast with the extra side, or the QS lunch is just too big for us, it at least fills us up more then getting just a muffin each!!!
Or if we are not going to use our snack credits for other stuff we will get a adult QS and use the Snack to get another side that tops up any of the meals without using everybodys snack credits, or by spending more money on meals, If we get hungry then we can always grab something else! but last yr out of the family of 3 adults and 3 kids we proberbly only actually paid out between us $50 extra for 3 wks sooooo nice to see all my money not go into my tummy
