Save the dates were just sent out and I've already been approached about "plus ones" (more like "I wonder who I'll bring for my plus one"). I am trying to figure out a polite way to say "adult only" as well as "by invite only" on our website, as well as on the invitations. I don't think addressing the envelopes as "Mr. and Mrs." rather than "and family" in combination with the reply cards will be enough of a hint. If it comes down to it, I will say something. But, since it is a destination wedding, I want to be clear up front.
Any suggestions appreciated!
