Top Mistakes People Make When Planning an Outdoor Event (and How to Avoid Them)

Russ Sizer • December 21, 2025

Outdoor events are fantastic. Fresh air, open space, and the freedom to create something truly unique. But while they look effortless when done well, outdoor events often come with hidden challenges that can catch people out.


At Zest Marquees, we’ve worked on weddings, parties, corporate events, festivals, and fundraisers across Northamptonshire and beyond. Along the way, we’ve seen a few common mistakes pop up time and time again. The good news? They’re all avoidable with a bit of planning.


Here are the top outdoor event planning mistakes — and how to steer clear of them.

 

❌ Mistake 1: Underestimating the Weather

British weather is famously unpredictable. One of the biggest mistakes is planning an event based solely on best-case weather.

How to avoid it:

Always have a weather-proof plan. A marquee provides shelter from rain, shade from the sun, and protection from wind. With optional sides, flooring, heating, and ventilation, your event can go ahead comfortably, no matter what the forecast throws at you.


❌ Mistake 2: Choosing the Wrong Size Space

Too small and guests feel cramped. Too large, and the event feels empty and cold.

How to avoid it:

Work with professionals who can recommend the right marquee size based on guest numbers, layout, catering, and entertainment. At Zest Marquees, we factor in everything from dining styles to dance floors so the space feels just right.


❌ Mistake 3: Forgetting About the Ground Conditions

Grass, uneven surfaces, mud, slopes — these are often overlooked until it’s too late.

How to avoid it:

Think beyond the marquee itself. Proper flooring makes a huge difference to comfort, safety, and accessibility. It also protects shoes, dresses, equipment, and furniture.


❌ Mistake 4: Leaving Things Too Late

Popular dates sell out quickly, especially on weekends and during peak seasons. Leaving marquee hire to the last minute can seriously limit your options.

How to avoid it:

Book early. Early planning gives you more choice, better layouts, and less stress. It also makes coordinating caterers, entertainment, and suppliers much easier.


❌ Mistake 5: Not Planning the Layout Properly

An awkward layout can disrupt the flow of your event — blocking walkways, cramping tables, or isolating key areas.

How to avoid it:

Plan zones: dining, dancing, bar areas, seating, and entrances. A professional marquee provider will help design a layout that flows naturally and keeps guests comfortable.


❌ Mistake 6: Overlooking Power, Lighting & Heating

Outdoor events don’t come with plug sockets or central heating.

How to avoid it:

Plan utilities early. From lighting and sound systems to heaters and catering equipment, everything needs power. Zest Marquees can advise on lighting, heating, and practical solutions to keep your event running smoothly.

 

❌ Mistake 7: Trying to Do Everything Yourself

DIY can be tempting, but managing an outdoor event on your own can quickly become overwhelming.

How to avoid it:

Use experienced suppliers. A professional marquee company doesn’t just supply a structure — they help guide decisions, spot potential issues early, and take the pressure off you.


✅ Plan Smarter with Zest Marquees

Outdoor events don’t have to be stressful. With proper planning — and the right support — they can be seamless, stylish, and unforgettable.

At Zest Marquees, we combine experience, quality equipment, and friendly service to help you avoid common pitfalls and create an event your guests will love.
