Escort card questions

You can do escort cards for couples, I would do it by last name to keep it easiest since then they wouldn't know which first name would go first.

For this situation it's also just easy to do a seating chart and forego escort cards since you are only assigning a table but up to you!

Thank you! And just organize them by whoever's last name is first?

I was going to list both if they have different last names - "Martha Smith and John Thomas"

Thank you!
