The short answer
AI travel planners in 2026 are structure generators, not fact databases. Use an LLM to build the skeleton (day-by-day flow, logistics logic, packing lists) and verify every concrete fact (opening hours, addresses, prices) against real sources - Google Maps, official sites, or travel APIs. The verification step is not optional.
The workflow that works
Step 1 - Generate structure with an LLM
Plan a 5-day trip to Kyoto in November.
Include: day-by-day outline grouped by neighborhood (minimize travel),
one highlight per day, realistic pace (2-3 sites/day),
restaurant types near each area, transport notes.
Step 2 - Verify everything concrete
- Addresses and hours: check Google Maps.
- Prices: check official sites.
- Seasonal events: check local tourism boards (the LLM will invent festivals).
- Reservations: many popular places need advance booking - the LLM won't tell you.
Step 3 - Iterate with feedback
Feed corrections back: "The temple is closed on Mondays; rework Tuesday's plan." LLMs handle iterative refinement well.
Common failure modes (2026)
- Hallucinated venues: plausible-sounding restaurants that don't exist.
- Stale information: post-COVID closures and changed hours.
- Overpacked days: the model optimizes for completeness, not enjoyment.
- Ignored logistics: transfer times between cities are usually underestimated.

FAQ
Can I trust an AI itinerary? Trust the structure, verify every fact. A verified AI itinerary beats both a hallucinated one and starting from zero.
Which LLM is best for travel planning? Any recent model; quality depends more on your verification loop than the model.
Does AI know current prices? No - prices change constantly. Always check booking sites.
