I will be sending out the save the dates soon and had questions about etiquette with these. Most of the couples we're inviting live together. But what should I do for couples that don't live together, I.e. My cousin and her boyfriend. Can I send the save the date addressed to the both of them to her place? I doubt he would really care to have his own. Also, for family all living together, can I send one save the date addressed to the family or should I be sending one to the parents, and one to each kid, etc. Thoughts? Thanks for any help!
