There is a lot of misinformation and confusion about the terms "Day of Coordination", "Month of Coordination" and "Event Management". To be honest, I've had the same package with all three names at one point, but finally settled on "Event Management". I'll explain why!
We re-named the "Day of Coordination" package to "Event Management" seeing that there are more hours spent prepping for a successful event prior to the wedding than the 10 hours or more worked on the actual wedding day. The day of the wedding we are indeed event managers and coordinate a seamless chaos-free wedding day because we have taken the time prior to the day of your wedding to review your planning with a professional eye.
In order to set you up for a successful well run event, we start at least around 6-8 weeks in advance. We take time reviewing all your planning, read through your contracts with a fine tooth comb, create a timeline with good flow, reach out to all your vendors to confirm details and logistics, have a walkthrough with your vendors at the venue around 6-4 weeks out, create floor plans, rain plans, guide you through any last minute changes and make sure there are no holes in your planning. There are at least 20-30 hours worked pre wedding and this begins more than a month out, so you see even the "Month of Coordination" package is not the best description.
Finally, there really isn't a "Day of Coordination" service. A professional coordinator who knows what it takes to have an event run smoothly would not show up on the day of a wedding and run someone else's timeline and details. There are too many moving parts and too many things to go wrong during an event. You do not want to pass the reigns off a few days before the wedding and hope all goes well. If a planner does sell that, WATCH OUT!
