How to check an AI itinerary in 10 minutes

ChatGPT and Gemini write a decent first draft. These seven checks, mostly in Google Maps, catch the mistakes before they cost you a morning.

Aino publishes this guide and is building a trip planning app of its own, launching in winter 2027. Every other app here is described from its own site and store listings, with prices dated.

Is ChatGPT good for planning trips?

For a first draft, yes. It knows which places people visit, a sensible order to see them in, and a few ideas you wouldn't have found. Where it struggles is anything that changes: opening hours, closed days, prices and whether a tour still has seats.

The best public test we know of is from May 2024. SEO Travel, a UK marketing agency, asked ChatGPT for 100 two day itineraries across ten cities and checked every line. 90% had at least one error. 52% scheduled a visit outside opening hours, 24% recommended a restaurant, café or attraction that had closed, and 25% sent travellers backtracking across the city (Travolution).

That test used ChatGPT 3.5, and newer models can search the web. The shape of the mistakes hasn't changed much, though. Places are usually right. Times are the problem.

Most people already sense this. In a Booking.com survey of more than 37,000 people in 33 countries, 42% said they always fact check AI travel advice and 29% do sometimes (Globetrender, August 2025). The checklist below is what that fact check looks like when you do it in ten minutes rather than an evening.

1. Does the place exist? (1 minute)

Type the exact name from the itinerary into Google Maps. If nothing comes up, or the pin lands in a different town, drop the stop. AI models produce names that sound right, and now and then they merge two real places into one that doesn't exist.

The worst case is rare but real. In September 2025 two tourists in Peru paid nearly 160 US dollars to be driven to a rural road near Mollepata, looking for a "Sacred Canyon of Humantay" that an AI had described. There is no such place. A local trek operator who saw their itinerary warned that this kind of error is dangerous at high altitude (AI Incident Database, incident 1636).

Most invented places are less dramatic: a café with a plausible name on a street that has no café. The one minute search catches both.

2. Is it open on that day? (2 minutes)

This is the classic ChatGPT itinerary mistake: a museum on the one weekday it closes. Lots of museums shut on a Monday or Tuesday, and the AI often doesn't know which.

Open each stop in Google Maps and read the hours block for your actual weekday. Arktikum, the science museum in Rovaniemi, is closed on Mondays from March to November and open every day from December to February. It also closes on 24 December (Arktikum, as of October 2026). An AI that learned the winter hours will send you to a locked door on a Monday in October.

While you're there, check public holidays in the country you're visiting. Those are the days a place is most likely to have special hours, which the business owner has to enter separately on its Google listing (Google Business Profile Help).

3. Do the hours match the slot? (2 minutes)

Being open that day isn't enough. The itinerary has to put you there while the doors are open. In the SEO Travel test, more than half the itineraries got this wrong at least once.

The usual version is a café slotted for breakfast that opens at 11, or a museum visit that starts 45 minutes before closing. Compare the start time on each line with that day's hours. Watch for last entry too: Arktikum stops selling tickets 30 minutes before it closes, and many bigger attractions stop an hour before.

If a slot is wrong, move it rather than deleting it. Usually the stop just needs to swap with the one after it.

4. How long between stops? (2 minutes)

AI drafts tend to group places by theme, so you get three museums in a row that sit in three corners of the city. That's where the 25% backtracking figure comes from.

In Google Maps, tap directions from each stop to the next, using the way you'll actually travel and roughly the time of day you'll travel. Write the minutes next to each line. If a leg is over 30 minutes and the stop isn't essential, cut it or give it its own half day.

Small distances can still cost time. Rovaniemi city centre to Santa Claus Village is about 8 km, which is about 8 minutes by taxi and 30 minutes on bus line 8 from the city centre stop (Santa Claus Village FAQ; Visit Rovaniemi bus 8 timetable, 2024 to 2025). An AI that says "a short hop" is right by car and wrong by bus. In winter, add 5 to 10 minutes to each drive for snow and for getting everyone into boots.

5. Is anything closed for the season? (1 minute)

Some places only run for part of the year: boat trips in summer, husky kennels in winter, a hilltop café that shuts in November. Others close for long renovations. The Pergamonmuseum in Berlin has been closed for renovation and is due to reopen on 4 June 2027, with some halls staying shut into the 2030s (visitBerlin). An AI that learned from older guides may still list it as a morning stop.

Open the official site for each big stop and look for a seasonal page or a notice at the top. This is the check that chatbots miss most, because the fact is only true for part of the year. When a reporter planned a March trip in England with Gemini, the draft missed seasonal restaurant hours and underestimated walking times in bad weather, according to a summary of her Wall Street Journal test (Let's Data Science, March 2026).

6. Are there still places on your date? (1 minute)

Open means the doors are open. It doesn't mean there's a seat on the 10 o'clock husky safari. An itinerary that reads perfectly can fall apart at the booking page.

Open the booking page for each ticketed activity and pick your real date. If it's greyed out, change the day now, while the rest of the plan can still move. Visit Rovaniemi, the city's official tourism site, warns that many activities sell out early from December to March and recommends booking in advance (Visit Rovaniemi, as of October 2026).

For Lapland specifically, we've listed which winter activities to book before you go and which can wait.

7. Does the day actually fit? (1 minute)

Add up door to door time, not activity time. A 45 minute husky ride near Rovaniemi is a 2 hour 30 minute programme, and the pick-up comes 15 to 90 minutes before the start (Bearhill Husky, Happy Trail tour, as of October 2026). That one line in the itinerary is most of a morning.

Then check daylight if you're going somewhere far north or south. On 15 January 2027 the sun is up in Rovaniemi from 10:19 to 14:34, so anything outdoors has about four hours to happen (sunrise-sunset.org).

If the day has more than two main things in it, cut one. Our guide to planning activities for a trip goes through the door to door method in more detail.

A worked example: one Rovaniemi day, checked

Say an AI gives you this for Friday 15 January: 09:00 Arktikum, 11:00 husky safari, 14:00 Santa Claus Village, 16:00 snowmobile safari, 20:00 northern lights tour. It reads well. Here's what the seven checks find.

The checked version is: husky safari in the morning, lunch, Santa Claus Village, Arktikum at 16:00, dinner, aurora tour if the sky is clear. Same ideas, one stop fewer, and nothing lands at a closed door. The full three day version is in our Rovaniemi winter itinerary with drive times.

Frequently asked questions

Is ChatGPT good for planning trips?

It's good for a first draft: places worth seeing, a rough order, ideas you hadn't thought of. It's weak on anything that changes, like opening hours, closed days and whether a tour has places left. In a May 2024 test by the agency SEO Travel, 90% of ChatGPT itineraries had at least one error. Use the draft, then check it.

What are the most common ChatGPT itinerary mistakes?

Visits scheduled outside opening hours, places that have closed, and routes that double back across the city. In the SEO Travel test, 52% of itineraries put at least one visit outside opening hours, 24% recommended a closed place and 25% needed backtracking or detours.

How do I check if a place in my AI itinerary exists?

Search the exact name in Google Maps. If nothing comes up, or the pin lands in another town, drop it. Then open the official website and make sure the name, address and photos match what the AI described.

Can ChatGPT check opening hours for me?

Only if it searches the web for that answer, and even then it reads whatever page it finds, which may be out of date. Ask it to search and to tell you the source and the date. Then confirm the hours for your exact weekday on Google Maps or the official site.

How long does it take to verify an AI travel itinerary?

About ten minutes for a three day trip if you work through the seven checks in order. Most of that time is in Google Maps: searching names, reading the hours block and tapping directions between stops.
