First, let me explain a small, but somewhat important detail. A wedding planner can be a wedding coordinator, but a wedding coordinator will not always be a wedding planner.
A wedding planner is often hired early in the process, typically before any major vendors are booked. She takes a very hands-on approach to the planning and designing of the event.
A wedding coordinator is sometimes referred to as a “day-of coordinator” and isn’t as hands-on in the creative process and their time to shine is about 6 weeks out from the wedding up until the week after your wedding, in some cases. Sometimes, a wedding coordinator can take on a few roles the wedding planner would take on, but those are usually add-on items, so be sure you have the discussion with her as to your needs/wants and expectations.
Hopefully that gives you a good idea between the two titles, so let’s jump into it.
