We have a no ring no bring policy. Unless we are friends with both people in the relationship, no one got a date. This mostly impacted FHs cousins (who we are not close to anyway). We did this knowing we were going against traditional etiquette, and would likely piss some people off, but honestly we didn't care, we didn't want people we dont even know at the wedding. Well it turns out we must not have pissed people off that badly, because the majority of the people impacted by this are coming to the wedding, and the few that are not are all out of state, and probably wouldn't come anyway.
The wedding is in a few weeks, and Fh and I haven't had to deal with any pushback. Im glad we stuck to our witts on this issue.
