I've gotten a few responses already and so far people that were given a guest are replying with just "guest". Part of the problem is I didn't realize that TK website doesn't prompt you to enter a real name when you RSVP online. Really wish I knew that before the invites went out. I was planning on doing a seating chart for tables but not actual escort cards. How would that work if I didn't know the guests names? Would just writing "John Smith & Guest" be OK? Contacting everyone we gave a guest to seems like a big hassle.
