Do you still cook for visiting grown up kids?

We have 4 children in their 30s/40s and 8 gc. They all live a distance away and sometimes choose to stay with us all at the same time. I am not a good cook and don't enjoy it so our habit is for each couple to choose a night to cook. Sometimes, though, I feel I should be an earth mother type who cooks lots of meals in advance to produce at the drop of a hat! What do you do?
