We have one or two people who were invited "with guest" and haven't given us a name for their guest. Part of the problem is that they didn't send their RSVP card back, just told us they were coming and mark two spots. Er. So, my question is, how do I give the unnamed guest an escort card? Or in those two cases, could I put "Ms. Jane Doe and guest" even if everyone else has their own individual?
