Give the group a simple structure
Start with the shared itinerary, then make the jobs and costs explicit. People do not need every detail; they need to know what affects their day and what they own.
One master itinerary
Keep transport, stays and anchor activities in a single timeline.
Small owners
Assign airport runs, reservations and equipment to named people.
Visible totals
Record shared expenses and make the balance understandable before departure.
Useful filters
Keep optional activities and personal reminders from obscuring the essentials.
Large does not have to mean noisy
A group chat becomes harder to search as more people join. Troupe gives the group a calm reference point while leaving conversation where it belongs.
Try Troupe for the next large group trip.
