Small-Group Tour or Coach Tour: What Changes at 12 People Versus 40

Two tours can list the same cities, the same hotels and the same sights and still be completely different trips, because one carries 12 people in a minibus and the other 40 in a coach. Group size is the least-marketed and most important line on the itinerary.
What a coach tour does well
- Price. Fixed costs split 40 ways are cheaper than split 12 ways.
- Comfort on long days: reclining seats, toilet on board, luggage handled by the driver.
- Predictability: the same route every week, hotels that know the group is coming, a leader who has done it a hundred times.
What it does badly
- Time. Forty people boarding, counting and finding the toilet adds 20 minutes to every stop.
- Access. Coaches cannot enter old-town centres, so 'visit Hoi An' becomes a walk from a car park.
- Restaurants and hotels have to hold 40 places, which narrows the choice to the ones that can.
What a small group does well
- Access to places a coach cannot go, and meals in ordinary restaurants.
- Flexibility on the day: a leader can move a visit earlier when the weather turns.
- Local transport where it is part of the experience: a public ferry, a night train, a tuk-tuk.
And its costs
- Higher price per person for the same route.
- Less physical comfort: minibuses on long days, luggage handled by you.
- One difficult person affects a group of 12 far more than a group of 40.
How to read the group size on an itinerary
Look for 'maximum group size', not 'average'. An average of 12 can mean 16 in high season. If the number is missing, assume it is large. Operators that cap groups say so in the first paragraph because it is a selling point.
