The prompt · ChatGPT

Organise a group trip.

People / constraints: [list]
Date window: [details]
Budget band feel: [details]
Destination known: [yes/no — details]
Who can be organiser: [optional]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. Decision steps with a deadline.
2. A fair cost-split approach.
3. Roles (booker, treasurer, comms).
4. A group message to kick it off.
5. Shared itinerary options (Sheet or Maps list).

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts, prices, opening hours or bookings. UK English.

Stay in this ChatGPT chat. Do not turn on apps or connectors, and do not use memory from another chat.

A short example
