A progressive dinner generally involves moving location for each meal course. We have done this in our neighborhood: House 1 serves appetizers; House 2 serves soup/salad; House 3 serves the main entree (usually something that does not involve extensive side dishes, such as chili or spaghetti); and House 4 serves dessert. Each house also is responsible for serving an accompanying beverage. If enough people are participating, additional people can be assigned as "helpers" for each house to bring the beverage(s), help serve, etc. The best tip I can give is to try to serve food that can be prepared ahead of time, heated quickly or doesn't need heating, and easily served. Otherwise the "owners" of the house with a meal course cannot easily participate in going to the other courses.
I'm not sure if you and your family live close enough to do this sort of traveling throughout the meal. Nonetheless, progressives can be a lot of fun!
