This page demonstrates how to craft an effective prompt to an AI language model (LLM) to create a comprehensive vacation itinerary tailored to your specific preferences. We'll use the example of planning a 7-day trip to Acadia National Park, flying into Portland, Maine.
The Challenge
Planning a multi-day vacation involves juggling dozens of decisions: where to fly, which hotels to book, what attractions to visit, where to eat, how to structure your time efficiently. Most travel guides offer generic advice. Tourism sites push chain hotels. You end up spending hours piecing together information from multiple sources.
An LLM can consolidate all this research into a personalized itinerary that reflects your values and preferences—but only if you ask the right way.
Why This Example Matters
Notice the complexity here. This prompt has multiple constraints and preferences:
- Specific starting point (Portland, Maine airport)
- Specific destination (Acadia National Park)
- Duration (7 days)
- Travel philosophy (non-chain hotels, ocean proximity, local dining)
- Implicit preferences (supporting local businesses, avoiding corporate tourism)
This isn't as straightforward as "give me a generic Maine trip." You're asking for an optimized itinerary that balances multiple objectives.
The Prompt Strategy
Notice how this prompt is structured:
- Clear trip parameters – Duration, origin, destination
- Specific constraints – Hotel preferences, dining philosophy
- Geographic requirements – Ocean proximity, route to Acadia
- Format request – Day-by-day breakdown
- Budget considerations – Price ranges for hotels and restaurants
- Practical details – Driving times, reservations notes
The Prompt
PROMPT
I'm planning a 7-day vacation to Acadia National Park in Maine. Here are my requirements:
- Flying into Portland International Jetport
- Want to explore coastal attractions and small towns on the way to Acadia
- Prefer independent, locally-owned hotels (not chain hotels) near the ocean
- Focus on local and regional dining experiences rather than chain restaurants
- Returning to Portland on day 7
Please create a detailed day-by-day itinerary that includes:
- Recommended route and driving times between stops
- Specific hotel recommendations with brief descriptions and estimated price ranges
- Must-see attractions and scenic stops along the way
- Restaurant recommendations for lunch and dinner (including cuisine type and price range)
- Suggested arrival/departure times to maximize daylight and travel efficiency
- Notes on which restaurants and attractions require advance reservations
- Alternative options for rainy day activities
Format as a day-by-day breakdown that I can follow while traveling. Assume I have a rental car and want to experience authentic coastal Maine.
Why This Prompt Works
1. Specific Trip Parameters
The prompt includes the origin (Portland), destination (Acadia), duration (7 days), and transportation method (rental car). This allows the LLM to calculate realistic driving times and structure the itinerary appropriately.
2. Clear Values and Preferences
By stating "locally-owned hotels" and "local dining," you're not just specifying hotel types—you're communicating your values. The LLM can now provide recommendations that align with supporting local businesses rather than generic tourism infrastructure.
3. Geographic Intelligence
Asking specifically for attractions "on the way" to Acadia shows you understand geography and want an optimized route, not random recommendations. This produces a logical itinerary rather than scattered suggestions.
4. Practical Requirements
Requesting price ranges, driving times, and reservation information means the itinerary is immediately actionable—you know what to expect budget-wise and what needs advance booking.
5. Contingency Planning
Asking for "rainy day alternatives" shows you're thinking practically about weather variability in Maine and want a complete plan, not just ideal-weather suggestions.
6. Format for Use
Requesting a "day-by-day breakdown" that you "can follow while traveling" means you get information organized for on-the-road reference, not a narrative essay about Maine.

How to Refine Your Prompt
PRO TIPS FOR VACATION PROMPTS
- Specify your travel style. Add details like "we prefer hiking" or "we want to relax more than explore" to personalize recommendations.
- Include dietary restrictions. If vegetarian, vegan, or allergic to shellfish, mention it so dining recommendations are appropriate.
- Mention group composition. "Traveling with two teenagers" or "romantic getaway" changes the recommendations significantly.
- Set budget parameters. State your nightly hotel budget clearly so you don't get recommendations outside your range.
- Request specific information. Ask for parking details, reservation windows, and operating hours rather than just attractions.
- Ask about seasonal factors. "What will September weather be like? What crowds should I expect?"
- Request backup options. "What if one restaurant is fully booked? What's your second choice?"

Why This Matters
This vacation planning example shows why LLM prompting is so valuable:
- Personalization at Scale. You get an itinerary tailored to your exact preferences, not a generic "top 10 Maine attractions" list.
- Local Knowledge Without Local Connections. You don't need to know someone in Maine. The LLM aggregates thousands of reviews and recommendations.
- Integrated Planning. Instead of juggling hotel booking sites, restaurant reviews, and attraction information, you get it all in one coherent itinerary.
- Real-World Details. Knowing what time to arrive to avoid lines, which places need reservations, and what activities work on rainy days—this is the difference between a good vacation and a frustrating one.
- Refinement Through Conversation. You can ask follow-up questions and adjust the plan in real-time without starting over.
Key Takeaway: Vacation Prompting Framework
When planning any trip with an LLM, include:
- Trip Logistics: Dates, duration, origin, destination, transportation
- Your Values: Budget level, accommodation preferences, dining style, activity interests
- Geographic Requirements: Routing preferences, distance tolerance, must-see destinations
- Practical Details: Group composition, special requirements, budget constraints
- Format Request: How you want the information organized for actual use
- Contingency Planning: Weather alternatives, backup options, flexibility notes
The result? A vacation itinerary that reflects your actual values and preferences, ready to execute when you arrive.
