TravelPlanner: Weather-Aware Itinerary Builder

Inspiration

Our inspiration came from a simple, universal frustration shared by travelers worldwide: having a perfectly planned trip ruined by unpredictable weather. We've all been there—booking an outdoor adventure only to be met with a week of rain, or planning a city tour during an unexpected heatwave.

Traditional travel tools are static; they act like simple to-do lists. They lack the intelligence to adapt to the most critical variable in any trip—the weather. We were inspired to create a tool that wasn't just a planner, but an intelligent companion that actively works to protect the user's travel experience.

What It Does

TravelPlanner is a "weather-aware" itinerary builder that empowers users to create resilient travel plans:

• Multi-Destination Planning: Create complex itineraries across multiple cities
• Weather-First Selection: View real-time forecasts before choosing activities
• Enriched Attraction Data: Powered by OpenTripMap API with custom classifications:
  • activity_category
  • estimated_cost_category
  • Indoor/outdoor status
• Interactive Builder: Drag-and-drop interface for easy scheduling
• One-Click Export: PDF or .ics calendar formats
• Privacy-First: No registration required, all data stored locally

How We Built It

Challenges & Solutions

1. Data Enrichment Challenge:

   • Raw OpenTripMap API data lacked structure
   • Solution: Built custom client-side engine (realActivityData.ts) to:
     • Infer activity categories
     • Estimate costs
     • Determine indoor/outdoor status

2. User Experience Challenge:

   • Initially planned cloud login system
   • Pivot: Adopted privacy-first, no-registration model
   • Result: Reduced friction while maintaining functionality

Key Achievements

✅ Data Enrichment Engine ("Secret Sauce")
✅ Interactive Itinerary UI with drag-and-drop
✅ Seamless User Flow from planning to export
✅ Practical Exports: PDF + iCalendar formats
