Plan the whole group trip in one place, so the planning doesn't eat into the vacation. Everyone sees the same plan, and no one gets stuck being the spreadsheet person.

A map ties the stops together so everyone knows where to be and when, without a dozen screenshots in the chat.

Anyone proposes a place, the crew votes, an organizer confirms. The booking details live on the trip, not buried in someone's inbox.

Drop in flights, rentals, tickets, and reservations with their confirmation numbers and files. The whole crew can pull up the details while you travel, instead of digging through one person's inbox.
A shared list for the crew gear, a personal one for your own, and an assignable to-do list so every task has an owner. Log expenses as you go and the ledger shows exactly who owes whom.

When you're back, everyone drops their photos into one shared gallery and reacts to the best ones. The trip lives on past the last drive home.
The usual group trip is held together by a chat, a sheet, a notes file, and a bill-splitting app that never agree.
Get the crew, the plan, and the money all in one place before you go. Including whoever still owes you from last time.
