Planning together
Two of you, four of you, ten of you: what changes
With two, a conversation is enough; from six you need roles. What changes with every group size — and when unanimity stops working.

A trip for ten is not five times the trip for two. The effort does not grow with the number of people but with the number of connections between them — and that grows quadratically.
With two there is one relationship. With four there are six. With ten there are forty-five. That is why what runs effortlessly with two suddenly stops working altogether above a certain size.
The threshold lies lower than most people think.
Two of you: coordination needs no tool
Two people plan in conversation. What has been decided, both know, because both were there. A list is a convenience, not a need.
What helps anyway: one place where the suggestions live — simply because three weeks later you no longer remember the name of the hotel you thought was "quite good".
What you can spare yourselves: roles, permissions, rules for deciding. Anyone introducing those with two people is building administration for a problem that does not exist.
Three and four: the point where it tips
The actual transition happens here, and it is almost always missed, because four people still feel like a "small group".
The first problem is not chaos but asymmetry. One person starts organising. The others let them — not out of laziness, but because that person has already started. After two weeks one person has the whole picture in their head and the others have questions. From then on the trip is a project with somebody in charge, and that was not the intention.
The countermeasure is banal and effective: invite everyone before anything is settled. Anyone who joins once half of it is booked no longer brings suggestions, only objections.
The second problem is silent assumptions. With two, you ask. With four, everyone thinks somebody else has already asked. That is exactly what a visible status on the suggestion is for: "checked", or else "open".
From five: roles stop being bureaucracy
From around five people, what would have been ballast before starts to pay off.
Three roles are enough. Owner (invites, removes), edit (enters, changes, reorders), read (sees everything, changes nothing).
The most common wrong decision is to distribute defensively — giving everyone read access only, "so nothing breaks". The reliable result is that one person plans the whole trip again and the others send her suggestions. You will then have introduced a tool and kept the very state you introduced it for.
Read is for the people who genuinely want it: the mother-in-law who is coming along but would rather not plan. The children. Everyone who only wants to know when you set off.
And it needs exactly one person who decides — not what gets done, but when collecting stops. That is the one task that cannot be distributed.
From eight: unanimity stops working
With eight people the probability that everyone agrees to a suggestion is practically zero — not because it is a bad one, but because with eight opinions there is always one against.
Anyone who waits for unanimity anyway gets one of two results: the group decides nothing at all, or the loudest person decides alone.
What works instead:
- Separate collecting from deciding, in time and visibly. For two weeks everything may go in. After that it gets sorted, and from then on nothing new is added.
- Ask for objection rather than agreement. "Who can not live with this?" produces an answer; "is everyone happy?" produces silence that is later taken for agreement.
- Give everyone a veto for exactly one thing. Remarkably effective: anyone who knows their one "no" counts gives way on everything else.
- Sub-groups for individual days. Not everyone has to do the same thing every day. A plan that holds ten people together for ten days is planning past reality.
From twelve: several vehicles, several schedules
Large groups rarely travel as a block. They come from different directions, at different times, in different vehicles.
What counts then:
- One plan, many views. Somebody who only wants to know where they are sleeping on Thursday should not have to read the whole tour.
- The meeting point matters more than the route. With twelve people in four cars the problem is not the way there but finding each other again.
- Book bindingly as soon as the number is settled. Accommodation for large groups is scarce, and "there are about twelve of us" is not a reservation.
- Expect a drop-out. With twelve people, experience says at least one pulls out. Anyone who plans for that does not have to rebook.
The table worth remembering
| Group size | What comes in | What is not needed yet |
|---|---|---|
| 2 | one place for suggestions | roles, rules |
| 3–4 | bring everyone in early, make the status visible | formal ways of deciding |
| 5–7 | assign roles, one person closes the collecting | sub-groups |
| 8–11 | ask for objection rather than agreement, sub-groups for days | a separate schedule per vehicle |
| 12+ | meeting points, binding bookings, a buffer for drop-outs | — |
What stays the same at every size
One thing never changes, and it matters more than anything in the table: next to every suggestion belongs the name of the person who brought it in.
With two that is superfluous, because you know it anyway. With ten it is the line that shows whether the trip really belongs to everyone — or whether the whole list came from two people and the others are only coming along.
What that looks like day to day — collecting suggestions, setting statuses, leaving gaps visible — is covered in Planning a holiday with friends. And what comes with packing together is under Sharing a packing list.
