We're not doing a grand exit from the church. Instead of a receiving line, we will be coming back in to dismiss guests from their rows. After that we will be heading back for a few portraits in the church. I don't want people milling about outside of the church thinking we're going to come out - but I can't figure a clear way to do it without seeming rude.
I was thinking something like printing in the programs, "After the ceremony please stay seated until the newly married couple comes to dismiss you. Then please head out to the reception site, we'll see you there!"
Does that make sense - any other suggestions??
