An in person or FaceTime/Zoom meeting is always a wonderful way to finalize the ceremony details.
With most meetings only taking 10 minutes a virtual conversation is the preference of most busy couples.
Do I run rehearsals? The short answer is no, not very often. With most Fridays - Sundays filled with weddings I am usually unavailable.
99% of all couples don't need their Officiant to guide their rehearsal. Every venue has an excellent wedding coordinator that has seen it all and can take you through what to expect.
