When we lived in Seattle, we hosted a Halloween/Samhain party each year for both pagans and non-pagans. We invited friends of all ages to join us for pumpkin soup, roasted turnips, hot cider, apple bobbing, and seed bread. The children were gathered for trick-or-treating (real food before the candy), and after we returned and the kids compared (and sometimes traded) loot, we'd begin the real party, starting with the sliced apple to reveal the star, and tales about the history of Samhain. At this point, non-pagan families who choose not to share in the divination, speaking with the dead, or honoring them, left. The rest of us joined in quieter work.
Now that we live in a rural town, people are less inclined to make the long drive for a celebration, but there are some traditions we continue. The kids still trick-or-treat in the neighborhood, and we still come home to do our good work for the holiday.
