Last Updated on March 9, 2025 by Tanya Janse van Rensburg

Planning your first event can feel like an overwhelming task, especially when there are so many moving parts to consider.

Whether it’s a wedding, corporate gathering, or a milestone celebration, it’s easy to get caught up in the excitement and overlook critical aspects that could affect the event’s success.

As a newcomer to event planning, understanding and avoiding common mistakes can save you time, stress, and potentially costly setbacks.

Here are five mistakes to avoid when planning your first event—and how to fix them.

1. Overlooking the Importance of a Realistic Budget

Mistake: One of the most common mistakes first-time event planners make is not setting a realistic budget from the start.

Without a clear financial plan, costs can quickly spiral out of control, leading to budget overruns and disappointment when the funds run dry.

How to Fix It:

  • Set a clear budget from day one: Break down the costs of the event into categories—venue, catering, entertainment, decor, and any other essential elements.

  • Prioritize your spending: Determine which areas are most important to you and allocate your budget accordingly. For example, if you’re planning a wedding, you might allocate more to photography and catering, while keeping the decor more cost-effective.

  • Include a contingency fund: Leave room in your budget for unexpected costs, such as last-minute décor additions or additional vendors.

2. Failing to Account for Timelines

Mistake: New event planners often underestimate the amount of time it takes to plan and execute an event.

Without a proper timeline, you might find yourself rushing to finalize details or, worse, missing critical tasks altogether.

How to Fix It:

  • Create a timeline: Start by setting clear milestones for each phase of the event planning process, from securing the venue to finalizing the guest list and confirming vendors.

  • Work backwards: Once you have your event date, plan backward to determine when each task should be completed.

  • Give yourself extra time: Always build in buffer time for unforeseen delays or changes in plans. This will help you stay ahead of the game and avoid panic as the event date approaches.

3. Choosing the Wrong Venue

Mistake: A venue is one of the most important components of any event, but many first-time planners choose a venue based on looks alone, overlooking practical concerns like location, capacity, and logistics.

Choosing the wrong venue can lead to poor guest experience and logistical headaches.

How to Fix It:

  • Consider your event needs: Make sure the venue matches the size of your event and accommodates all of your needs—whether it’s a stage for performances, room for catering, or accessibility for guests with special needs.

  • Think about logistics: Is the venue easily accessible for your guests? Is there ample parking or public transport nearby? Ensure the venue has all the necessary facilities, such as bathrooms, power outlets, and proper lighting.

  • Visit in person: Always visit the venue in person before making a commitment. Take note of the layout, atmosphere, and any potential limitations that might affect your event.

4. Neglecting to Vet Vendors Properly

Mistake: Poor vendor selection is another common pitfall for first-time event planners.

Whether it’s a caterer, photographer, or entertainer, working with unreliable or inexperienced vendors can leave you with a bad outcome on the day of the event.

How to Fix It:

  • Do your research: Take the time to read reviews, check references, and ask for recommendations. Don’t rely solely on online reviews—reach out to previous clients to get a sense of their experience.

  • Meet with vendors in person: Meeting face-to-face will help you get a feel for their professionalism and commitment to your event. You’ll be able to ask questions and ensure they align with your vision.

  • Check contracts: Always have a clear written agreement in place with your vendors, outlining their services, payment terms, and cancellation policies. This helps prevent misunderstandings later on.

5. Ignoring the Guest Experience

Mistake: New event planners often focus so much on the logistics, décor, and details that they forget to consider the guest experience.

An event might be beautifully planned, but if guests aren’t comfortable or entertained, it won’t leave a lasting impression.

How to Fix It:

  • Think about comfort: Ensure your venue has adequate seating, climate control, and restrooms. Provide easy access to food, drinks, and entertainment to keep your guests comfortable and engaged throughout the event.

  • Engage your guests: Consider activities, games, or entertainment that will keep your guests engaged. Whether it’s a fun icebreaker for a corporate event or a photo booth at a wedding, interactive experiences can make your event memorable.

  • Provide clear communication: Make sure your guests know exactly where to go, what to expect, and when to arrive. You can send out reminders, use signage at the event, or even create a schedule to keep guests informed.
