Outcome

Carley Thornell, a working parent, spent a few hours going back and forth with ChatGPT to plan a four-day London trip with their 6-year-old, ending up with a spreadsheet itinerary. On the ground, hotel concierges caught what it missed: a V&A exhibit sold out since day one with no walk-ups, a way into the British Museum's Egypt wing when general tickets were gone, a nut-free restaurant pick (Ping Pong) that had closed the previous year despite a 'permanently closed' flag on Google, and suggested bus routes 11 and 15 that don't go to the Science Museum or Hamleys. A rail strike the week they were there wasn't something ChatGPT could know. Some of its dining picks still worked out for the family.

ChatGPT

The source didn't share its exact prompt, so we wrote this from what it describes.

Let's work this out together. I'll tell you what I know, you suggest options and ask what you need, and we'll narrow it down step by step. Nothing gets booked, bought or sent until I say so.

Goal: Plan a realistic family city break day by day, and flag everything I need to double-check before we go.

What I'll share as we go:
- City, dates and where we're staying: [DETAILS]
- Who's coming (ages) and any allergies or needs: [DETAILS]
- Things we'd love to see and do: [DETAILS]

Rules:
- Group each day by neighbourhood so we're not criss-crossing the city.
- For every attraction, say whether tickets need booking ahead and whether it might sell out.
- For every restaurant, check it's still open and mark allergy information as something to confirm with them.
- Give transport by line or route number only if you can check it on the official transport site; otherwise say so.
- Add a rainy-day backup for each day.
- Ask for my OK before you pay, book, send, submit or cancel anything.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.

Output: A day-by-day plan in a table, with a 'check before you go' list.

You'll know it worked when: nothing on the plan is closed, sold out or impossible to reach when we get there.
