reception only save the date wording?

Save the dates are *almost* ready to go out (yay!) We are having a private ceremony followed by a larger reception in las Vegas. I want to send save the dates to people who are invited to the reception only, so they have time to make travel arrangements if they are going to attend, but I also want to make it clear from the start that they are invited only to the reception, so there are no hurt feelings later, when the invitations go out. I've seen a lot of wording samples for invitations to reception only, and samples for traditional wedding save the dates, but no save the date for our reception samples. I can't be the first bride ever to do this. Any of you ladies have some ideas for me?
