Group trips have a lot of moving parts. Flights, accommodation, deposits, headcounts, dietary restrictions, RSVPs that go quiet, and the friend who confirms 3 weeks late.

A checklist doesn't remove the complexity. It removes the chance of forgetting something important.

Use this as your master reference from the first "we should do this" message to the moment everyone touches down at home.

6 Months Before: The Foundation

The further out you plan, the better your options and the lower the prices.

Confirm the trip is actually happening. One direct conversation, not a group chat thread. Is there real commitment here, or is everyone just enthusiastic about the idea?
Get everyone's budget range. Per person, excluding flights. Do this before you choose a destination.
Agree on a destination. Use TripRelay to create a shared room and put 3–4 curated options to a group vote.
Set a decision deadline. "We're deciding by [date]" is a real thing you need to say out loud.
Identify a planning lead. One person is accountable for keeping things moving.
Confirm rough dates. Not the exact dates yet, just the general window. Weekend trip? Full week? Are you targeting a specific event?
Check passport requirements. If this is international, who needs to renew? Processing times are currently 8–11 weeks for standard applications.

3–4 Months Before: Book the Big Things

Prices go up and availability goes down. Book now.

Lock the final dates. Run a Doodle or When2Meet poll if you haven't already. Book around the person with the most constraints.
Get a firm headcount. Set an RSVP deadline. Anyone not confirmed by that date is excluded from headcount planning.
Book accommodation. Vacation rental or hotel block. For vacation rentals, confirm the guest limit and house rules.
Book flights. Set a group deadline: "Everyone books their own flights by [date]." Unbooked friends are their own problem after that date.
Set up a shared expense tracker. Splitwise works well. Add everyone and use it from day one.
Start a shared trip document. Google Docs, Notion, or your TripRelay room. One place with all the information.
Check visa requirements. For international trips, visa timelines vary significantly by nationality and destination.

6 Weeks Before: Activities and Details

Vote on must-do activities. Use TripRelay to present activity options and let the group vote. Builds the itinerary around what everyone actually wants.
Book activities in advance. Popular tours, restaurants, and experiences fill up. Use Viator to find and book group-friendly options.
Make restaurant reservations for group dinners. Most restaurants need 2–3 weeks notice for groups of 6+. Some need more.
Confirm transportation. Airport transfers, rental cars, party bus. Book it.
Collect accommodation deposits. If you're paying upfront, invoice the group now. Give a payment deadline.
Create a shared itinerary. TripRelay generates a day-by-day itinerary based on your group's votes. Or build one manually. Either way, get it written down.
Confirm everyone has travel insurance. Optional but recommended, especially for international trips with expensive bookings.

2 Weeks Before: Final Prep

Send the full itinerary to the group. One message. All the details: accommodation address, check-in time, activity schedule, restaurant reservation times.
Collect all outstanding money. Accommodation, any shared group purchases, activity deposits. Close the tab.
Confirm all bookings. Call or email venues if anything feels uncertain. Confirmation numbers for everything.
Set up the group money plan for the trip. Who pays for what on the road? Who tracks it in Splitwise? How often do you settle?
Brief the group on local customs. Tipping norms, dress codes (especially religious sites), currency situation, phone plan recommendations.
Check weather. Not to overthink it, just to know what to pack.

48–72 Hours Before: Almost There

Send a final logistics message. Meeting point, arrival times, who's picking up the rental car, where the Airbnb key is.
Download offline maps. Google Maps lets you download areas for offline use. Do this before you lose cell service.
Screenshot all confirmations. Flights, accommodation, activities. Offline access matters.
Pack a group essentials kit. Sunscreen, basic first aid supplies, a portable charger. Someone should have this.
Share your itinerary with someone at home. A family member or friend who isn't coming. Just in case.

Day Of: Departure

Group meeting point confirmed.
All accommodation details shared with everyone (not just the person who booked).
Emergency contact list. One person in the group has everyone else's numbers and knows the plan.
Group fund or Splitwise active. Everyone knows the protocol.
Go.

On the Trip: Day-to-Day

Settle Splitwise at the end of each day. Don't let it build up for 4 days.
Confirm next-day plans each evening. Keeps everyone aligned; prevents the morning scramble.
Check activity start times the night before. "The tour leaves at 9am" is only useful information if everyone knows it.

After the Trip

Final Splitwise settlement. Do this within a week. Memory fades fast.
Share photos. A shared Google Photos album or iCloud shared album. One place for everything.
Start planning the next one. Seriously. The best time to book the next group trip is while everyone is still riding the high from this one.
