6 adults and 6 kids, WWB.
I too have pre-cooked sausages, breadsticks. Also assorted crisps, nice ham, cheese, mini-pizzas, biscuits (for mid morning and afternoon snacks), 2 frozen desserts, yoghurts (for the kids, if necessary), veg for dipping, grapes, umm, and will be buying bread fresh tomorrow. So I suspect we should have enough food.
