Using AI to Plan Your Trip: ChatGPT vs. Google Gemini

Planning a vacation used to mean drowning in open browser tabs, cross-referencing guidebooks, and struggling with spreadsheets. Today, artificial intelligence promises to do the heavy lifting in seconds. But not all AI chatbots are created equal when it comes to travel logistics. We tested the two industry leaders—OpenAI’s ChatGPT and Google’s Gemini—to see which one could build a superior 3-day itinerary for a trip to Paris. The results revealed distinct strengths for each platform depending on what kind of traveler you are.

The Experiment: A 3-Day Paris Itinerary

To make this a fair fight, we used the exact same prompt for both AI models. Specificity is key when dealing with AI, so we avoided vague requests like “Plan a trip.”

The Prompt: “Create a detailed 3-day itinerary for a first-time couple visiting Paris in May. We have a daily spending budget of €250 (excluding hotel). We love Impressionist art, vegetarian food, and want to avoid the biggest tourist traps. Include specific restaurant names and estimate travel times between locations.”

Here is how the two giants compared on creativity, logistics, accuracy, and user experience.

ChatGPT: The Creative Concierge

When we ran this prompt through ChatGPT (specifically using the GPT-4o model), the result felt like reading a blog post from a knowledgeable travel writer.

Strengths

  • Narrative Flow: ChatGPT understands “vibe.” Instead of just listing locations, it explained why we were going there. It suggested starting the day with a walk through the Jardin des Tuileries because the morning light is best for photos.
  • Specific Dining Recommendations: It nailed the vegetarian request. It recommended Le Potager du Marais for traditional French cuisine made vegetarian, explaining that reservations are essential.
  • Hidden Gems: It listened to the “avoid tourist traps” instruction. Instead of suggesting lunch on the Champs-ÉlysĂ©es, it directed us to MarchĂ© des Enfants Rouges in the Marais district for a more authentic food stall experience.

Weaknesses

  • Outdated Information: While generally accurate, ChatGPT occasionally struggles with real-time changes. It suggested a museum that is currently undergoing partial renovations without noting it.
  • Lack of Visuals: Unless you ask it to generate an image (which is AI-created, not a photo of the place), it is a text-heavy experience. You have to leave the app to see what these places look like.

Google Gemini: The Logistical Mastermind

Google Gemini (formerly Bard) approaches travel planning differently. Because it is integrated into the Google ecosystem, it prioritizes data, maps, and logistics.

Strengths

  • Google Maps Integration: This is the killer feature. After generating the itinerary, Gemini provided a dynamic link to Google Maps with the route already plotted. You could see exactly how far the MusĂ©e d’Orsay is from the lunch spot.
  • Real-Time Data: Gemini pulls from Google Search in real-time. When we asked about flights, it showed current prices from Google Flights. It correctly identified that May 1st is a public holiday in France (Labor Day) and warned that many shops might be closed, a detail ChatGPT missed in the initial pass.
  • Visual Context: The results included actual photos of the locations pulled from Google business listings, giving an immediate sense of the atmosphere.

Weaknesses

  • Robotic Tone: The itinerary was functional but dry. It felt more like a checklist than a curated experience.
  • Generic Descriptions: While it found vegetarian restaurants, the descriptions were often just “Good ratings on Maps,” rather than a description of the signature dish.

The Day-by-Day Breakdown

Here is a look at the actual output differences for the “Art Day” (Day 2) of our Paris request.

ChatGPT’s Day 2

  • Morning: Visit the MusĂ©e de l’Orangerie to see Monet’s Water Lilies. “Arrive at 9:00 AM sharp to beat the crowds.”
  • Lunch: Picnic in the Tuileries Garden. It suggested buying baguette sandwiches from Boulangerie Bo&Mie.
  • Afternoon: Walk across the Seine to the MusĂ©e d’Orsay.
  • Dinner: L’Arpège. (Note: This was a mistake. L’Arpège is a 3-Michelin star restaurant that would blow the entire €250 daily budget in one meal. ChatGPT often hallucinates on pricing tiers).

Gemini’s Day 2

  • Morning: MusĂ©e d’Orsay. It noted the ticket price is currently €16.
  • Lunch: Le Grenier de Notre-Dame. It correctly identified this as the oldest vegetarian restaurant in Paris.
  • Afternoon: Exploring Saint-Germain-des-PrĂ©s. It included a “Google Hotels” widget showing prices for nearby stays if we hadn’t booked yet.
  • Logistics: It provided a specific bus route (Bus 63) to get from the museum to the lunch spot, including the 12-minute travel time.

How to Get the Best Results

Regardless of which AI you choose, the quality of your itinerary depends on your prompt engineering. Use the R.O.C. method for travel planning:

  1. Role: Tell the AI who it is. (“Act as a luxury travel agent” or “Act as a budget backpacker guide”).
  2. Objective: Be specific. (“Plan a 3-day trip focused on WWII history”).
  3. Constraints: Set limits. (“Do not include museums that cost more than $20,” or “Walking distance only”).

Best Prompts for ChatGPT

  • “Give me a list of 5 restaurants near the Eiffel Tower that are popular with locals, not tourists.”
  • “Write a packing list for Paris in November based on current fashion trends.”
  • “Tell me the history of Montmartre as if you were a storyteller.”

Best Prompts for Google Gemini

  • “Find flights from NYC to Paris for under $600 in May and add them to my calendar.”
  • “Show me a map of all the vintage clothing stores in the 11th arrondissement.”
  • “Check the opening hours for the Louvre for next Tuesday.”

The Verdict

Who wins the battle for the best Paris itinerary?

Winner for Logistics: Google Gemini If you need to know how to get from Point A to Point B, check opening times, or visualize your route on a map, Gemini is superior. Its integration with Google Flights, Hotels, and Maps makes it a powerful assistant for the “booking” phase of travel.

Winner for Discovery: ChatGPT If you are in the “dreaming” phase, ChatGPT is better. It uncovers romantic spots, explains cultural nuances, and creates a more cohesive narrative for your trip. It feels like getting advice from a friend who used to live there.

Recommendation: Use them together. Start with ChatGPT to get creative ideas and build the skeleton of your trip. Then, feed those locations into Google Gemini to verify opening hours, check prices, and build your map.

Frequently Asked Questions

Can AI actually book the flights and hotels for me? No. Neither ChatGPT nor Gemini can currently execute financial transactions. They can find the flights and provide links to booking sites (like Expedia or the airline direct), but you must enter your credit card information and finalize the purchase yourself.

Do I need the paid version of ChatGPT for travel planning? The free version (GPT-3.5 or limited GPT-4o) works well, but the paid version (ChatGPT Plus) allows for web browsing. This is critical for travel. Without web browsing, the AI relies on old data and may recommend restaurants that have closed permanently.

Can I export the itinerary to my phone? With Google Gemini, you can export the results directly to Google Docs or Gmail, which is very convenient. With ChatGPT, you typically have to copy and paste the text into your notes app, though you can ask it to format the output as a table for easier copying.

How accurate are the price estimates? Treat all AI price estimates as rough guidelines. Prices for food and tickets fluctuate dynamically. Always verify the actual menu prices on the restaurant’s official website before you go.
