We're mostly seeing this issue with cousins from the same generation as us living with our aunts/uncles.
A couple of notes here:
- Children below the age of 18 are not invited because we're having an adult-only wedding
- We will not be giving plus ones to any family members who are not engaged or living with their significant other
- I've written "we've reserved ___ seats in your honor" on all of the response cards and left a couple lines above for them to write their names in
- For everyone else we're writing "Mr. & Mrs. John & Jane Doe," so would "Mr. & Mrs. John & Jane Doe + Family" be appropriate with "we've reserved 3 seats in your honor" ? Or would this be confusing if the third person, the adult child, is not specified?
