How to Plan Travel with AI: Real-World Experience and a Complete Avoid-Pitfalls Guide

According to the TakeUp 2026 Report, about 45% of travelers use AI to plan their trips, triple the rate in 2023. But most people just "ask once and go" — asking ChatGPT, "Give me a 7-day Japan itinerary," getting a suggestion, and following it blindly.

I did this too, and the results were mixed:

• ✅ AI suggestion to enter via New Chitose on Jan 1st and stay in Sapporo → Correct! The airport is great for shopping, and Sapporo has many options.
• ❌ AI recommended a seafood izakaya that "looked great" → In reality, it had closed down long ago.
• ⚠️ AI didn't warn about reservation requirements for Jan 1st restaurants → Discovered only after another AI reviewed the plan.

A better way: Treat AI as a "personal travel guide," not a "one-time suggestion tool." This article shares my practical experience:

• How to integrate your flight, hotel, and preferences into AI (Claude Projects / Gemini Gems).
• Letting one AI review another AI's itinerary (Crucial! Catching blind spots).
• Asking AI anytime during the trip for changes (rain, delays, discovering new spots).
• Which information must be checked on official websites (AI makes mistakes).

---

📌 TL;DR

• Current State: 45% of travelers use AI, but "ask once and go" leads to pitfalls.
• My Lesson: AI recommended closed restaurants, but the Jan 1st airport entry advice was correct.
• Solution: Claude Projects for data integration + AI-to-AI review (Key) + Official site verification.
• Real Value: Adaptability during the trip, faster than Google, and emotional support.
• Checklist: Restaurant operating status, reservation requirements, Jan 1st airport entry choice.

My Experience Planning a Japan New Year Trip with AI

Experience 1: AI Recommended a Closed Restaurant

Gemini's Suggestion:

Sapporo Must-Eats:
1. Susukino Seafood Market
2. Nijo Market Seafood Izakaya "○○"
3. Tanukikoji Genghis Khan BBQ "△△"

Reality Check:

• Googled "Nijo Market ○○" → Shows "Permanently Closed".
• "△△" BBQ shop had changed its name; AI gave the old one.

Lesson: According to AFAR Magazine tests, AI training data has a cutoff date and doesn't know the latest operating status.

Experience 2: AI Suggested Staying in Sapporo on Jan 1st (Got this right!)

AI's Suggestion:

Jan 1st Arrive at New Chitose Airport → Stay in Sapporo directly
- Spend time at the airport first (New Chitose is great for shopping)
- Head to Sapporo city in the evening
- Go to Otaru or Hakodate the next day

Why this suggest was correct:

• New Chitose Airport is open on Jan 1st: Drugstores, souvenir shops, and Ramen Road are all open.
• Sapporo is livelier: Even if some shops are closed on Jan 1st, there are still more options than in smaller cities.
• Entering via Hakodate would be terrible: Most shops in smaller cities are closed on Jan 1st; it would be very boring.

Discovered after another AI reviewed:

I fed the itinerary to another AI for review:

AI pointed out key insights:
✅ Entering via New Chitose on Jan 1st is a good choice (airport can be explored for 2-3 hours)
⚠️ But be aware:
   - Most restaurants in Sapporo city are closed or fully booked on Jan 1st
   - Suggest booking restaurants 2-4 weeks in advance
   - Or eat at the airport before heading to the city
⚠️ If entering via Hakodate:
   - Fewer options in a small city
   - Jan 1st will be very boring

Lesson:

• Airport entry/exit choice is crucial: For Jan 1st arrival, choose New Chitose (Sapporo), not Hakodate.
• Airport is the Jan 1st savior: New Chitose Airport is an attraction itself, no fear of having nowhere to go.
• Let AI review each other: The second AI will remind you of risks you didn't think of.

4 Steps to Build Your AI Travel Guide

Step 1: Use Claude Projects to Integrate All Travel Data

Problem: It's annoying to re-explain the background (dates, budget, accommodation) every time you ask AI.

Solution: Claude Projects lets you upload all documents, and AI automatically remembers the context.

Setup Steps (Requires Claude Pro $20/month):

1. Create Project: Login to Claude → Projects → Create "Hokkaido Winter Trip 2026"

2. Upload Documents:

   • Flight confirmation PDF
   • Hotel bookings
   • Food list (compiled from Tabelog, Google Maps)
   • JR Pass rules

3. Set Custom Instructions:

# Hokkaido Winter Trip 2026 Planning

## Basic Info
- Time: 2026/1/10-1/17 (7 days 6 nights)
- People: 2 Adults
- Budget: Total 100,000 TWD

## Itinerary Framework
- D1: Taipei -> Sapporo (Arrive 18:00)
- D2-D3: Sapporo City
- D4: Otaru Day Trip
- D5: Hakodate

## Preferences & Constraints
- Preference: Food > Sightseeing
- Hate waking up early: Start itinerary after 10:00 AM
- Constraint: Just after New Year (1/1-1/3), some restaurants need reservations

Actual Effect: After this, whenever you ask a question, Claude automatically references the context without needing repetition.

Free Alternatives:

• Paste a "Background Info Paragraph" at the start of every chat.
• Organize in Google Docs, copy-paste to AI.

Step 2: Use Gemini Gems to Create a Custom Guide

Gemini Gems allows you to create a "dedicated AI assistant" with preset preferences.

Setup Example: Create "Hokkaido Food Guide" Gem

You are my Hokkaido travel food expert.

My Preferences:
- Local small shops > Tourist restaurants
- No raw food
- Budget per meal TWD 500-1000
- Avoid shops with >30 min queue

Your Task:
1. Automatically filter out raw food when recommending restaurants
2. Note if reservation is needed and queue time
3. Use Google Maps to verify latest opening hours
4. Remind about special operating status during New Year (1/1-1/3)

Effect:

• Every time you ask "Sapporo lunch recommendation," it automatically applies your preferences.
• The Gem proactively reminds you about reservation requirements and opening hours.

Step 3: Let AIs Review Each Other (Crucial!)

Core Concept: An itinerary made by one AI is critiqued by another to catch blind spots.

Real-world Case:

Step 3.1 - ChatGPT Generates Itinerary:

Give me a Hokkaido 7-day itinerary (1/10-1/17),
Budget 100,000 TWD, 2 people, focus on food.

ChatGPT gives: Sapporo 3 days → Otaru 1 day → Hakodate 2 days.

Step 3.2 - Feed ChatGPT Itinerary to Claude for Review:

This is the Hokkaido itinerary ChatGPT gave me, please critique and find issues:

Angles:
1. Are there transport connection issues?
2. Is the schedule too tight?
3. Which attractions might be closed in winter?
4. Is the budget allocation reasonable?
5. Anything to note for the post-New Year period (just after 1/1)?

[Paste ChatGPT's full itinerary]

Claude's Response (Real test):

Analysis found 3 issues:

⚠️ Issue 1: Otaru to Hakodate transport
- ChatGPT wrote "Otaru direct JR to Hakodate"
- Reality: Need to transfer in Sapporo
- Correct route: Otaru → Sapporo → Hakodate

⚠️ Issue 2: Post-New Year crowds
- 1/2-1/3 Sapporo city restaurants are full
- Suggest booking in advance or adjusting itinerary order
- Could go to Otaru, Hakodate first (fewer people)

⚠️ Issue 3: Budget allocation
- Hakodate accommodation estimate TWD 3,000 is too low
- Reality approx TWD 4,500
- Suggest adjusting other expenses

Value:

• ChatGPT is good at creative routes but lacks rigor in details.
• Claude analyzes rigorously, catching transport, crowd, and budget issues.
• Two AIs complement each other, avoiding single blind spots.

Step 4: Build a Verification Checklist (What to Check on Official Sites)

Although AI is convenient, these 6 items must be confirmed manually:

✅ Official Site Check List

1. Opening Hours & Closed Days

• ❌ AI Common Mistake: Giving summer hours, not knowing winter shortage hours.
• ✅ Correct Action: Check attraction official site.
• Case: Asahiyama Zoo Winter 10:30-15:30, AI often gives 9:30-17:15.

2. New Year Special Hours (Japan New Year focus!)

• ❌ AI Doesn't Know: Most shops closed on 1/1, partially open 1/2-1/3.
• ✅ Correct Action:
  • Check attraction/restaurant official site for "Year-end New Year Info".
  • Search "New Year" or "Shogatsu" in Google Maps reviews.
  • Airport is savior: New Chitose Airport operates normally on 1/1, good for 2-3 hours.
• Lesson: Entering via New Chitose on 1/1 and staying in Sapporo was right (many choices), Hakodate entry would be boring.

3. Is the Restaurant Still Open

• ❌ AI Common Mistake: Recommending closed restaurants (old training data).
• ✅ Correct Action:
  • Google Maps check "Open" or "Permanently Closed".
  • Tabelog check latest review date.
• Lesson: 1 of 3 restaurants in my collection had closed.

4. Reservation Requirements

• ❌ AI Common Mistake: Recommending popular spots without warning "Reservation Needed".
• ✅ Correct Action:
  • Google Maps reviews search "Reservation".
  • Must book 2-4 weeks early for New Year period.

5. Transport Schedules

• ❌ AI Common Mistake: Giving last year's or summer schedules.
• ✅ Correct Action: Check JR Hokkaido Official Site.

6. Exact Event Dates

• ❌ AI Common Mistake: Giving last year's dates.
• ✅ Correct Action: Check event official site.
• Case: Sapporo Snow Festival 2026 is 2/4-2/11 (changes slightly every year).

Verification Tools:

• Google Translate Lens: Photo translate Japanese official sites instantly.
• Chrome Browser Auto-Translate: Right click → Translate to English/Chinese.
• Google Maps Reviews: Read latest reviews to confirm operating status.

AI Guide During Travel: Adapting Faster Than Google

Use Case 1: Sudden Heavy Snow

Traditional Way: Google "Sapporo rainy day indoor spots" → Read articles → Compare distances → Check hours → 30 Minutes.

AI Guide Way (5 Minutes):

Sapporo heavy snow today (30cm accumulation),
Need indoor alternatives for Hokkaido Shrine plan.

My status:
- Staying near JR Sapporo Station
- Free from 3 PM
- Dinner reservation at 7 PM

Give me 3 backups, and explain why they suit snowy days.

AI Response (Combined with Projects background info):

Based on your location and time, recommending 3 indoor snow day plans:

1. **Sapporo Beer Museum**
   - Distance: Subway 15 min
   - Time: 3:00-5:30 (2.5 hours enough)
   - Feature: Indoor tour + Beer tasting (Warm up)

2. **Tanukikoji Shopping Street**
   - Distance: Subway 10 min
   - Time: 3:00-6:30
   - Feature: Covered arcade, snow-proof, drugstores/souvenirs

3. **Daimaru Department Store**
   - Distance: Walk 5 min
   - Time: 3:00-6:00
   - Feature: Indoor heating, underground food street

⚠️ Snow day note:
- Wear non-slip shoes or buy simple ice cleats
- Leave for dinner at 6:30 PM, allow buffer

Emotional Value: AI says "Snow days have their own fun!" (Encouraging) instead of cold Google results.

Use Case 2: Adding a Suddenly Discovered Spot

Prompt:

I found a super beautiful cafe in Otaru (not in original plan),
Want to stay 1 extra hour.

Adjust subsequent itinerary, ensure I'm not late for 19:00 Sapporo dinner.

Current Time: 14:00
Current Location: Otaru Canal

AI Quick Response:

Received! Adjusting for you:

✅ Added Cafe (14:00-15:00)
⏰ Adjusted Schedule:
14:00-15:00 Cafe
15:10-16:30 Rokkatei + Souvenir shopping (Compressed 30 min)
16:40-17:20 Kitaichi Glass (1F only)
17:30 JR back to Sapporo
18:15 Arrive Sapporo
18:45 Arrive at Restaurant (Buffer allowed) ✅

💡 Optimization:
- Rokkatei focus on "Buying" not "Eating"
- Return to Sapporo early to avoid rush

Emotional Value: AI doesn't say "You messed up the plan," but "Found a good spot! Adjusting for you" (Supportive).

---

Conclusion: AI is a Guide, Not Google

Core Concept:

Most people treat AI as a "Smarter Google" — Ask once, get answer, end.

Better Way: Treat AI as a "Personal Guide" — Continuous dialogue, adjustment, adaptation.

This method saves you:

• ⏰ Time: 7-day planning from 20 hours → 3-4 hours
• 💰 Money: Avoiding AI errors (Closed restaurants, Jan 1st closed spots)
• 😌 Stress: Ask AI anytime during trip for changes (Faster than Google)
• ❤️ Emotional Value: AI encourages and suggests (Warmer than cold search results)

But you can't skip:

• Official Site Verification (1 hour): Hours, Closed days, Reservations
• AI-to-AI Review (10 mins): Catching single AI blind spots
• Flexibility: Don't plan too rigidly, weather and transport can change

---

Action Advice:

✅ Next Trip Planning:

• Try Claude Projects or Gemini Gems (Integrate your data)
• Let one AI review another AI's itinerary (Crucial!)
• Use "Must Check List" to verify key info (Especially New Year)

✅ During Trip:

• Ask AI anytime (Weather, delays, discoveries)
• More context given = More accurate advice
