Do you really need a rehearsal? In nearly all cases, I say yes.
Even if it’s just a phone call between you, your fiancé(e), and your officiant, make sure and talk through the ceremony before the wedding . It’s a low pressure way to figure out details that will be much more time-sensitive and urgent on your actual wedding day.
As part of my work with couples, I “cruise direct” their rehearsals. Based on that experience, I’ve put together a guide on how to run a rehearsal. (Most important: Know who’s walking down the aisle before the rehearsal happens.)
You’ll find that guide, and other free wedding planning resources, here.
