How to Use AI to Plan a Solo Trip Without Landing on a Tourist Trap Itinerary

I was standing in line at the Trevi Fountain in 2019, shoulder-to-shoulder with about 400 other people, when I realized I'd done everything wrong. The gelato place I'd found on a "hidden gems" list had a 45-minute wait. The "authentic" restaurant served microwaved lasagna. Every recommendation came from the same recycled travel blog content, and I'd followed it like a lemming. So when I started using AI to plan trips last year, my first question was simple: can this thing actually find places that aren't already overrun?

The Prompt That Changed Everything

My first attempts were disasters. I asked ChatGPT for "off the beaten path restaurants in Lisbon" and got the same five places that show up on every TripAdvisor list. The Timeout Market. The pink street. Time Out literally publishes a magazine about being mainstream.

Then I tried something different. Instead of asking for recommendations, I asked it to think like a local. The prompt that finally worked: "You're a 35-year-old graphic designer who lives in Alfama and hates tourists. Where do you actually eat dinner on a Tuesday night? Not places you'd recommend to visitors. Places you go."

The shift was immediate. It stopped listing attractions and started describing neighborhoods. It mentioned a tascas that doesn't have an English menu. A bakery that closes at 2pm because the owner's been doing this for 40 years and doesn't care about dinner service. Specific street corners where locals drink cheap wine outside after work.

I couldn't verify everything before traveling, but I saved the names and cross-referenced them with Google Street View. Real places. Small. No "featured on" stickers in the windows. When I got there, about 70% of the suggestions were genuinely good. The other 30% either didn't exist anymore or weren't as good as described. But that's a better hit rate than I've ever gotten from travel blogs.

What Completely Failed

AI is terrible at timing. I asked for a walking itinerary through Porto and it casually suggested hitting six neighborhoods in one afternoon. When I actually walked it, the route was physically possible but emotionally exhausting. It doesn't understand that you need to sit down. That sometimes you just want to watch pigeons for 20 minutes. That jet lag is real.

I also learned that ChatGPT will confidently make up opening hours. It told me a specific market in Valencia opened at 8am on Sundays. It opens at 10am. It told me a museum in Copenhagen was free on Wednesdays. It's free on Tuesdays. I started adding "verify this information before going" to every prompt, which helped remind me not to trust it blindly, but didn't actually make it more accurate.

The hallucinations are sneaky too. It once recommended a "small family-owned bookshop" in Amsterdam that I could not find any evidence of existing. Not on Google. Not on Maps. Not on any Dutch website I could translate. I spent 20 minutes searching before accepting it had invented a cozy little store out of thin air.

The Kick: Use AI to Interview Yourself First

Here's the thing nobody talks about. The best use of AI for solo trip planning isn't getting recommendations. It's figuring out what you actually want.

Before my last trip, I had ChatGPT interview me. I prompted it: "Ask me questions about my travel preferences, one at a time, like you're a travel agent trying to understand what kind of trip I actually want. Don't give suggestions until you've asked at least 10 questions."

It asked things I'd never thought about. Do I prefer mornings or evenings? Do I want one base or multiple locations? How do I feel about eating alone at restaurants versus getting takeout? What's my walking tolerance in kilometers? What makes me feel lonely versus happily alone?

By the end, I had a clearer picture of what I wanted than I'd ever had before. I learned I don't actually like museum-heavy days even though I always plan them. I learned I need at least one "do nothing" afternoon or I get cranky. I learned I prefer neighborhoods with good coffee over neighborhoods with famous sites.

Then I fed all those answers back and asked for an itinerary. The result wasn't some surprisingly effective hidden gem list. But it was paced right. It had the kind of balance I actually needed. The AI remembered I said I hate lines, so it didn't suggest anything that typically has a wait. It remembered I like morning walks, so it built in early routes before crowds.

The Layering Technique

I've started using what I call layering. First conversation: the interview. Second conversation: rough itinerary based on those answers. Third conversation: I paste in the itinerary and ask it to poke holes. "What's missing? What would a local critic say about this plan? What am I going to regret?"

That third pass caught things I would've missed. It pointed out I had no backup plan for rain. It noted that two of my dinner spots were in the same neighborhood, so if one was closed, I'd have to scramble. It suggested keeping one evening completely unplanned because "solo travelers often find their best experiences through spontaneous encounters."

Was that last part a bit generic? Sure. But it was also right.

I still don't fully trust AI for addresses, hours, or anything that requires current information. But for the shape of a trip—the rhythm, the pacing, the self-knowledge part—it's genuinely useful. The question I keep coming back to: why did it take a chatbot asking me questions to realize I don't actually enjoy the trips I've been planning for years?
