Most group trips are planned in a Frankenstein stack: itinerary in Google Docs, dates in a WhatsApp poll, expenses in Splitwise, bookings in eight different browser tabs. Here's the honest landscape in 2026.
What the categories look like
Itinerary builders — Wanderlog, TripIt, Google Travel. Great for solo or couple trips. Get clunky the moment six people need to edit at once.
Expense splitters — Splitwise is the default. Solid for the math, weak for the context (which trip was this? who was actually in?).
Generic collab tools — Notion, Google Docs, Trello. Maximum flexibility, zero opinionation. You'll spend 20 minutes setting up the doc before anyone plans anything.
Booking aggregators — Booking, MakeMyTrip, Skyscanner. Built for individual purchases, not group sign-off.
What's missing in the stack
Four gaps no popular tool closes well:
- Live group decisions — polling dates or destinations across a 6-person chat is brutal.
- One itinerary, many edits — real-time co-editing without overwrites.
- Bookings + expenses in one ledger — today's flight booking is tomorrow's settle-up.
- An AI that drafts, not dictates — group trips need AI that listens to the room and proposes.
How to pick
- Trip under 4 people, simple itinerary → Google Docs + Splitwise is fine.
- 4–8 people, multi-city → upgrade to a collaborative planner with built-in polling and split tracking.
- Recurring group (annual trips, college reunion, family) → invest in a single source of truth so each new trip starts from the last one's template.
The "right" stack is whichever one your group will actually open on day three of the trip — not the one with the prettiest landing page.
