Is it okay to use one place card for each couple? To save room, I thought it would be easier to put two people on each place card. Can this also work for two people who come together who aren't dating (i.e. someone brings a friend instead of a date)?
Also, do I need to put last names on the place cards? A few of our guests have the same first name, but I figured they would be able to figure out which one is theirs based on their spouse's name on the card. Does that work?
