I would not serve alcohol. If they are newly sober their counselors or sponsors most likely told them to stay away from it. people, places, and things. Sobriety is so fragile...is it really worth it? Last year my mom did not allow alcohol and I was glad. Had there been alcohol I would have gone to my local alano club instead of my parents house. My sobriety comes first. However I would be ok with it this year, maybe because I have more sober time. It really is a personal choice.
