FI and I got a return from a couple that will only be coming to the ceremony, and not attending the reception. We weren't planning on doing a recieving line right after the ceremony, do we have any obligation to go out of our way to greet & thank them for coming? Our plan was after the ceremony to exit straight into the limo and then we're doing recieving line during cocktail hour...I'm pretty sure we don't have an obligation but just wanted to see what you lovely ladies thought!
