We live in Vegas and our wedding is being held here. So I guess slightly "traditional" in the sense we have a big guest list, rented a large venue, whatever. Neither of us belongs to a church, we aren't religious, so we are using a suggested officiant from our venue. Aka someone we don't know. At all. We are totally okay with that, but I know it is common for the officiant to be invited to the rehearsal dinner and wedding reception. Is that still necessary with an officiant we have practically no relationship with???
