How many of you actually followed proper etiquette and if someone over the age of 18 was invited to the wedding but stilll lived at home with their parents, did you send them a seperate invite or did you send it including them with their family? I know etiquette dictates if a guest is over 18, they should get their own invite, regardless if they are still living at home or not ... If I don't have to send those that still live at home over the age of 18, their own invite, I'm saving myself lots of moolah on extra invites for them ...
