If invited guests do not respond to a formal wedding invitation, even though a response card was supplied, should we call them to find out if they will come? Or can we assume that they're not coming?
As far as final head count goes, you should never assume. Call to see if they're coming. You never know -- maybe they think they sent the response card but it may be hiding under a pile of mail. If calling is a problem, assume that they are coming, and make sure there’s food and seats for them. It's better to have extra grub and room than to have neglected guests wondering where to sit!
