10 Common Wedding Day Mistakes (and How a Coordinator Helps You Avoid Them)

There’s no sugarcoating it: your wedding day can either feel like a dream or a total whirlwind—and sometimes both at once. With so many moving parts, it’s easy for small hiccups to spiral into big headaches if you’re not prepared. That’s exactly why having a wedding coordinator on your side is more than just a luxury—it’s your best defense against chaos.

Let’s walk through 10 of the most common wedding day mistakes couples make, and how a professional wedding coordinator (like me!) helps keep them from happening in the first place.

1. Not Building Enough Time Into Your Timeline

The mistake:
Couples often build a timeline that looks good on paper—but doesn’t account for real-life delays. Makeup runs long, Uncle Bob’s missing when it’s time for family photos, or it takes 15 extra minutes to bustle your dress.

How a coordinator helps:
We build buffer time into key parts of the day, and we’re constantly adjusting in real-time. If hair and makeup go long, we shift things to ensure you’re not rushed down the aisle. No one will feel the scramble—because we’re handling it behind the scenes.

2. Forgetting to Eat or Stay Hydrated

The mistake:
It’s way too easy to run on adrenaline and excitement… and forget food and water entirely. Dehydration, low blood sugar, and even fainting? Yep—it happens more often than you think.

How a coordinator helps:
We come prepared with water bottles, protein bars, and a gentle reminder that no one wants a hangry bride (or groom!). We check in regularly, especially during photos and prep, to make sure you're staying fueled.

3. DIY Setups Running Behind

The mistake:
Couples who DIY their décor or rely on friends/family to set up often run out of time—or find the results aren’t exactly what they imagined.

How a coordinator helps:
We arrive early and handle setup exactly the way you envisioned. Whether it's placing centerpieces, checking the ceremony layout, or making sure your signage is straight, we take your vision and make it reality—on schedule and stress-free.

4. Vendor Miscommunication

The mistake:
Not every vendor reads your timeline closely, and sometimes they have questions on the day-of. If there’s no one to direct them, those questions fall on you or your family.

How a coordinator helps:
We reach out to vendors before the wedding to confirm arrival times, logistics, and contacts. On the day-of, we’re the point person—so you're not answering vendor calls while getting your makeup done.

5. Overlooking the Ceremony Details

The mistake:
Chairs not aligned. Aisle décor missing. Bridal party unsure where to stand. Music cues missed. These tiny errors can distract from a really meaningful moment.

How a coordinator helps:
We run your ceremony rehearsal and triple-check the layout. On the wedding day, we cue the processional, fix crooked chairs, adjust the officiant’s mic, and make sure your walk down the aisle is everything you hoped for.

6. Trying to Manage the Day Yourself

The mistake:
Even the most organized couples fall into this trap—thinking they can manage the day-of because “it’s just a timeline.” But timelines don’t run themselves.

How a coordinator helps:
We live in timelines. And more importantly, we handle what the timeline doesn’t show—delays, tricky guests, sudden weather changes. Your job is to soak up every moment. Ours is to keep the machine running quietly in the background.

7. Not Having a Rain Plan (or a Backup to the Backup)

The mistake:
Outdoor weddings in Wisconsin? Beautiful… but unpredictable. Couples sometimes avoid making backup plans because they “don’t want to jinx it.”

How a coordinator helps:
We make solid Plan Bs—and we communicate them to vendors and guests before the weather hits. If we need to move the ceremony inside or delay setup, we’re ready. And we’ll be the ones carrying umbrellas or grabbing towels, not you.

8. Letting Family Drama Steal the Show

The mistake:
Weddings can bring out deep emotions, and sometimes tension—especially with blended families, divorced parents, or over-involved relatives.

How a coordinator helps:
We’ve seen it all, and we know how to be your buffer. We gently redirect nosy guests, shield you from behind-the-scenes drama, and make sure your energy stays protected. You shouldn’t be playing referee in your gown—we’ve got it handled.

9. Skipping the Details (That Actually Matter)

The mistake:
Sometimes couples spend so much energy on big-picture planning that small—but important—details slip through the cracks. Think: Who moves the gifts? Who lights the candles? Who has the marriage license?

How a coordinator helps:
We check—and double check—the little things. From pinning boutonnieres to collecting sentimental items post-ceremony, we’re your second set of eyes and hands, always a few steps ahead.

10. Not Having Someone to Wrap It All Up

The mistake:
The end of the night arrives, and suddenly no one knows who’s packing up the cards, rentals, or personal décor. It’s late, everyone’s tired, and family ends up scrambling.

How a coordinator helps:
We create a cleanup and pack-out plan before the big day. Whether we’re placing your guestbook in your car or helping coordinate pickup with rental vendors, we ensure a smooth wrap-up—so you leave with memories, not a to-do list.
