I am organizing my son's wedding (he and his fiancee live abroad but wanted to marry in our hometown). We do not have a wedding coordinator, but a woman in our church handles all weddings and will be the one directing the rehearsal, lining the attendants up to enter the church at the actual wedding, etc. We are fond acquaintances but not really friends. It seems to me that we should invite her to the reception, but what do others think? And if so, should I do it by sending her a wedding invitation, which mentions the rehearsal, or by sending her a note inviting her and her husband to the reception?
