Hi guys! Trying to figure out the best etiquette for addressing save the dates. I have a couple of guests on my list that have significant others of a few months or less. I plan to address guests and any s.o. on the actual invites when they go out. However the wedding is more than half a year away--things can happen and who knows if they'll be together months down the road. So my question is: do I address both of them on the save the dates? Or just wait until I send out the invites? Thanks!
