I've been lurking around different boards for a while, and I apologize in advance if this question has already been asked. My fiancé and I are getting married next July. Because most of our guests live out of state (some out of country), we want to give them enough notice about our date; I recently started looking at different ideas for save the dates and found some that I like, which then brought up my question. I have some cousins who are over the age of 18, but still live with at home with their parents. I heard (and am subsequently under the assumption) that anyone who is over the age of 18 gets an invitation regardless of their living situation. First, I want to make sure this is correct. Second, as far as save the dates go, do I still have to send separate ones to my aunts/uncles and their children over the age of 18?
