This is something I had completely not thought about. I didn't think they were really necessary so I hadn't asked anyone to do this role.
The way our room will be set up is people will already be sitting at their assigned tables for both ceremony and reception, so guests would need to be taken to their assigned table. Would I need ushers in this situation and if so how would I handle this? Or would just doing a seating chart for the guests and letting them find their table themselves suffice?
