Running an event for 20 people is straightforward. Everyone can see everyone. You can read the room. Adjust on the fly. Running an event for 100 people is a different beast entirely.
The margin for error shrinks. Small problems become big problems. And if you lose momentum, getting it back is nearly impossible.
We've run events for groups of 100+. Here's what we've learned about keeping large events from falling apart.
The pre-event work matters more
For a small event, you can sort teams on the day. For a large event, that's a disaster waiting to happen.
We get the guest list in advance and pre-assign teams. Usually 6-8 people per team, mixed across departments. This does two things: it stops the finance team sitting with finance (defeating the point), and it means people know exactly where to go when they arrive.
Think of a seating plan at a wedding. Same principle.
No milling around. No confusion. Everyone finds their table, sits down, and we start.
More actors, more structure
A 20-person event might have 3 actors. A 100-person event needs 6-8.
Not because we're scaling up proportionally, but because with more teams, you need more characters available for interrogation at any given time. Nobody wants to wait 20 minutes to question a suspect - it's a surefire way for them to lose interest quickly.
We also run tighter schedules. Clear time blocks for evidence review, interrogations, team discussions, and the final accusation. Less flexibility, but it keeps 100 people moving in the same direction.
The room setup
Round tables. Always round tables.
Long banquet tables look nice in photos but they're rubbish for team discussions. Half the team can't see the other half. Side conversations take over. People at the ends get left out.
Round tables force everyone into the conversation. And for 100 people, you need a venue that can fit 12-15 of them with enough space between for people to get up and head to the interview areas.
If you're booking your own venue, this is the thing most people get wrong. They book a room that fits 100 people theatre-style and then wonder why it feels cramped when you add tables. Make sure you get a space that's big enough to accommodate the movement.
Keeping energy up
Large groups have momentum problems. Some tables race ahead. Others get stuck. The gap widens and suddenly you've got teams finished and bored while others are still on the first clue.
We build in catch-up mechanisms. Hints delivered to struggling teams. Progress updates that create urgency without embarrassing anyone. And dramatic moments that reset everyone's attention at the same time.
It's choreography as much as facilitation.
The reveal
For small events, the big reveal is intimate. Everyone gathered close, watching the answer unfold.
For large events, you need production value. Microphones. A clear stage area. Sometimes a screen if the room is big enough that people at the back can't see facial expressions.
The reveal has to land for everyone, not just the front row.
Is bigger better?
Depends what you want.
Large events are brilliant for getting a whole company or department together. The shared experience creates stories people tell for months. "Remember when Sarah accused the wrong person and nearly flipped the table?"
But if your goal is deep team bonding, smaller groups work better. More airtime per person. More intimate discussions. Easier to observe individual dynamics.
Sometimes it works better to split 100 people into two events of 50 if your budget allows.
