AI Trip Planning Guide 2025: Workflow, Prompts & Tool Chaining

Q: Do I still need guidebooks?

They add cultural depth; AI accelerates planning not nuanced context.

Q: How do I stop hallucinated transit times?

Verify with official transport sources then overwrite AI placeholders.

Q: Best model for planning?

Pair a general LLM with flight, lodging and activity vertical tools for accuracy.

Why AI Planning Beats Manual Only

Advantages

Compress research timeline 60–70%
Rapid scenario comparison
Early surfaced constraints
Consistent export format

Limitations

Needs human timing validation
Inventory availability must be checked
Occasional hallucinations for niche locales

Core 6-Step Workflow

Define Trip Envelope: Dates, travelers, budget band, interests.
Generate Skeleton: Broad AI prompt (see template below).
Refine Constraints: Ask AI to compress transfers, cluster geography.
Inject Live Data: Replace placeholders (flight prices, train times, tour slots).
Risk Pass: Identify overpacked days & adjust buffers.
Export & Track: Move to spreadsheet / Notion with status tags (Booked / Hold / Research).

Prompt Templates (Copy & Adapt)

You are a precise 2025 travel itinerary assistant. Build a 5-day plan for: [DESTINATION]. Travelers: [# + profile]. Budget: [band]. Interests: [list]. Constraints: minimize backtracking, include 1 sunrise & 1 night food tour, mark activities needing pre-booking. Output table: Day | Morning | Midday | Afternoon | Evening | Approx Cost (USD) | Notes (flag weather dependencies).

Add iterative follow-ups: "Condense transfers", "Propose cheaper alternates for Day 3 afternoon", "Insert a low-impact activity alternative".

Lock a refundable base early via Hotels.com deals then refine day-level flow.

FAQ

Do I still need guidebooks?

Use them for evergreen context; AI accelerates assembly, not deep cultural insight.

How do I stop hallucinated transit times?

Always verify with live sources (Rome2Rio, official rail sites) then overwrite placeholders.

Best model for planning?

Use a general LLM for structure + specialized search/price tools for facts.

Next: Price flights (search now), secure lodging (rentals), add protection (insurance).
