I'm helping a relative put together invitations. The ceremony/reception venue cautioned her and her mother that any guests that run late will not be allowed into ceremony. The guest entrance to the ceremony is at the "front" rather than "back" so those doors will have close at the start, and no guests will be able to "slip in the back." *Yes, I understand all guests should be on time anyway, but there are typically some stragglers.*
Is there a polite way to include a note to guests in the invitation. Perhaps on the directions card? If so, any suggestions to how to word this? My relative and her mother are very concerned, so I told them I would ask on here.
