If you invite a guest and make it clear that they are the only one invited, meaning they don't have a SO, no kids, you didn't address the invite +1, they RSVP'd for 1. What do you do if they actually show up to the wedding with someone? What happens if there is no room for the person, like if you have a seating chart and tables are full?
This is purely hypothetical, but the thought crossed my mind the other day, and now I'm really curious as to how this situation would be handled. Share your stories and solutions please.
