We are getting our reception details figured out and have a question. How do you address the escort cards; is it Mr and Mrs blah blah? first and last names? what if someone is bringing a guest and you don't know their name? Or does each individual person get their own? We are using rocks, since we are getting married at Starved Rock, with the names of places we have visited as table markers instead of numbers.I'm interested to hear what others think. Thanks,Patti
