Hey there, event planners!

Planning an event, whether it’s a corporate function, a wedding, or a milestone celebration, is no small task. It’s exciting, sure, but it also comes with its fair share of challenges. And trust me, I’ve seen it all! From last-minute venue panics to budgets that mysteriously disappear (where does all that money go?), there are some classic mistakes that can turn a dream event into a logistical nightmare.

But don’t worry, I’ve got your back! Here are five common event planning mistakes and how to avoid them like a pro.

1. Not Setting a Realistic Budget

Ah, the budget. It’s the thing no one really wants to talk about but is absolutely crucial to get right. One of the biggest mistakes I see? People setting an unrealistic budget and then wondering why they’ve run out of money halfway through planning.

💡 Avoid it:

✔ Start with a detailed budget breakdown: venue, catering, entertainment, styling, transport, everything.

✔ Don’t forget the hidden costs (think service fees, permits, and contingency funds for last-minute surprises).

✔ Always get quotes before making decisions - you’d be surprised how quickly costs can add up!

💬 Pro tip: Give yourself a buffer - at least 10-15% extra for unexpected expenses. That way, if something goes over, you’re covered!

2. Choosing the Wrong Venue for Your Event

Your venue sets the entire tone for your event, but it’s not just about aesthetics. A gorgeous location is great, but if it doesn’t have the facilities, space, or flow to suit your event, it can cause some serious headaches on the day.

💡 Avoid it:

✔ Consider logistics - Does the venue have enough space? Is there good access for guests and vendors? What’s the weather contingency plan?

✔ Check what’s included - Some venues offer tables, chairs, and AV, while others are just a blank canvas.

✔ Think about the guest experience - Is there parking? Is the location easy to find? Will guests be comfortable?

💬 Pro tip: At Sequoia Estate, we offer an exclusive-use venue with plenty of space, a stunning marquee oval, and flexible styling options—so you can create the event you really want without compromising on logistics.

3. Leaving Things to the Last Minute

Event planning takes time - more than you think! One of the biggest mistakes I see is people underestimating how long things take to organise. Booking vendors, finalising details, and managing RSVPs all need time, and if you leave it too late, you might end up scrambling.

💡 Avoid it:

✔ Start early - venues and top suppliers book out months (even years!) in advance.

✔ Create a timeline with key deadlines - bookings, deposits, menu tastings, invitations, etc.

✔ Have a clear run sheet for the day so everyone knows what’s happening when.

💬 Pro tip: The earlier you book, the more choices you have. Plus, some vendors offer early-bird discounts, so you could actually save money!

4. Forgetting About Guest Experience

You might have an amazing event planned, but if your guests feel lost, bored, or uncomfortable, that’s what they’ll remember.

💡 Avoid it:

✔ Ensure the layout is comfortable and functional - seating, shade (if outdoors), and easy access to food and drinks.

✔ Keep guests engaged - interactive elements, great entertainment, and a smooth flow from one part of the event to the next.

✔ Don’t underestimate food and drinks - hungry guests are grumpy guests!

💬 Pro tip: Little details matter! At Sequoia Estate, we love helping clients create thoughtful touches - whether it’s a stylish welcome area, comfy lounge zones, or late-night snack bars to keep the energy up!

5. Not Having a Backup Plan

Even with the best planning, things can go wrong - weather changes, suppliers cancel, or unexpected hiccups arise. The biggest mistake? Not having a contingency plan.

💡 Avoid it:

✔ Weather plan? Sorted. If you’re outdoors, make sure there’s an indoor or covered option available.

✔ Supplier issues? Plan B. Have backup options for key vendors in case someone pulls out.

✔ Technical failures? Spares. Bring extra cables, chargers, and check AV setups in advance.

💬 Pro tip: At Sequoia Estate, we help you think through all the what-ifs, so you can relax knowing you’ve got everything covered.
