How to use AI to plan a trip itinerary

You booked five days in Rome. You have a list of “must-sees” from three different friends, and a growing suspicion that you can’t fit the Vatican, the Colosseum, and a cooking class into one Tuesday.

AI is good at turning a pile of wishes into a day-by-day plan. It’s less good at knowing whether that museum is open on Mondays. So it drafts, and you check.

What you’ll end up with

A day-by-day itinerary grouped by area, plus a checklist of what to confirm before you go.

Before you start

Your destination, dates, and where you’re staying
Who’s going, and anything that matters: kids, a bad knee, a strong opinion about breakfast
Your list of things you’d like to see or do
A rough sense of budget: shoestring, moderate, or treat-yourself

Driving between several cities? Our guide to planning a road trip with AI covers routes and drive times.

Step 1: Describe the trip and get a first draft

“Two adults, we walk a lot, we hate early mornings” gets you a better itinerary than “a fun trip to Rome.”

Try This Prompt

Plan a day-by-day itinerary for my trip.

Destination: [E.G. ROME, ITALY]
Dates: [START DATE TO END DATE, OR NUMBER OF DAYS AND THE MONTH]
Where we're staying: [NEIGHBORHOOD OR AREA]
Who's going: [E.G. TWO ADULTS IN OUR 50S]
Pace: [RELAXED / MEDIUM / PACKED]
Budget level: [E.G. MODERATE]
Things we'd like to see or do: [YOUR LIST]
Anything to plan around: [E.G. ONE OF US CAN'T WALK MORE THAN AN HOUR AT A TIME, NO EARLY STARTS]

Rules:
- Each day, either stay near where I'm staying or go to ONE other area and come back. Never put two different areas on the same day.
- Only use places from my list.
- Give each day a morning, afternoon, and evening, with no more than 3 main stops per day.
- For each stop, say roughly how long to allow.
- Don't give opening hours, ticket prices, schedules, closing days, or whether tickets are required, not even "usually." Mark any stop that might need a ticket or might be closed some days with the word CHECK.
- Don't name specific restaurants, shops, or tours, and don't include links. Say what kind of place to look for and in which area.
- Use the pace I gave, including in the title and any labels.
- If something on my list doesn't fit, say so and suggest which day it could replace something.
- Leave half a day free somewhere in the trip.

Day 3 — Vatican City

Medium pace · One other area · A major sightseeing day

…

Afternoon — Vatican Museums

Allow 2–3 hours · CHECK

Prioritise the galleries and highlights that interest you most. The museums are extensive, so a selective visit is more comfortable than trying to cover everything.

Some AI tools search the web as they go and add restaurant names, links, or facts like ‘closed on Mondays’ with a source attached. Treat each one as a lead. Check that the place still exists and that the source actually says what the AI claims.

The free half day isn’t laziness. It’s where the plan goes when it rains, or when someone’s feet file a formal complaint.

Step 2: Check the distances in a maps app

Open each day in Google Maps or Apple Maps and look at the walking or transit time between stops. If a day has you walking 50 minutes between two places it called “nearby,” ask the AI to swap things around. Check the areas, too. A day that goes to one area, back for a rest, then out to a different area breaks the one-area rule.

Try This Prompt

I checked the itinerary above in a maps app. Here's what I found:
[E.G. "DAY 2: THE WALK FROM STOP 1 TO STOP 2 IS 45 MINUTES, NOT 15"]

Rearrange only the days I mentioned so that the travel time between stops is shorter. Keep the other days exactly as they are. Use the travel times I gave you instead of your own estimates.
- Each day, either stay near where I'm staying or go to ONE other area and come back. Never put two different areas on the same day.
- If a day breaks the rule, move a stop to another day; don't just tell me how.

Then check that every place from your list is still somewhere in the plan, and put back anything it dropped. In testing it deleted two stops instead of moving them. Check each day against the one-area rule yourself, too.

Step 3: Turn the plan into a checklist of things to confirm

Try This Prompt

Make a checklist from the itinerary above of everything I should confirm on official websites before the trip.

For each stop, list:
- What to check (opening days and hours, whether tickets must be booked ahead, entry rules, prices)
- What kind of source to check it on (e.g. the attraction's official website)

Don't tell me the answers yourself. Only list what I need to check. Put it in a table with a blank column called "Confirmed" for me to fill in.

Work through the table and fill in what you find. If a day falls apart, paste the facts you found back into the chat and ask it to fix only that day.

Step 4: Make it something you can use on the trip

Ask for a short version you can keep on your phone: “Turn the final itinerary into a one-screen list per day, with the stops in order and the neighborhood for each.” Save it somewhere that works offline. Hotel Wi-Fi has opinions.

When it goes sideways

Every day is packed? Say “Cut each day to 2 main stops and move the rest to a ‘maybe’ list.”
