I have always been taught and firmly believe that single guests should have a plus one (and I have been the single guest miserable at a wedding because I didn't have a plus one, thought I would be seated with friends, and was seated alone at a sad single's table that made us feel like misfit toys). However, now that I'm having a small family wedding to accommodate covid restrictions, do I have to give plus ones to my cousins? My single aunts and uncles will be getting them because, even though I need to keep the guest list small, I do think it's nice for them to have a travel companion if they want one (many will be traveling long distances). But all of my cousins will be there with their siblings and parents, so I feel like it's different? Am I totally deluding myself here?
