I spring for the feast, every year. I do this willingly, for selfish reasons. You see, I am quite a decent cook, and picky about proper preparation. My family, not so much. so, I tell them that if they have a dish that they are very fond of, they can bring it. But, I make a wide variety of traditional dishes, as well as some more exotic choices, that I like. So, I am never disappointed.
However, I EXPECT everyone to help clean up. I use Chinet plates and disposable cups and utensils, foil pans and paper napkins, to reduce the dishes, and put trash cans around for easy disposal.
Also, the leftovers are all mine. See, I told you I was being selfish.
