I would like to use the same formal address format for my save the dates and invitations. I will NOT be using a second inner envelope for the invitation. I have two questions...
1) How do I address a married couple with only one child?
a. Mr. and Mrs. John Doe
Child's fist name
b. Mr. and Mrs. John Doe and Child's first name
c. Mr. and Mrs. John Doe and Family
d. The Doe Family
2) A tricky question of etiquette...We are having a destination wedding, which we don't expect many will be able to attend. We are not very close to my dad's family. My parents think we should only send invites to aunts and uncles on my dads side plus add "and family" at the end to imply that my cousins are invited. Most of my cousins are grown up and living on their own or have their own families started. I know proper etiquette says you should send them to each person older than 18 or those that are married, but is this an exception? Any better suggestions?
