Travel planner

### Problem
- Travel planning is fragmented: flights, hotels, activities, budget – all in different tabs.
- No personalized recommendations based on past trips & tastes.
- Intimidating for domestic travelers in Russia (especially less-explored regions).

### Solution
- One smart request: user inputs destination, dates, budget, group type, past liked places, activity preferences.
- AI generates a complete package:
> Transport (trains/planes)
> Hotels & apartments
> Must-see sights & hidden gems
> Daily activities & local food spots
> Real-time budget breakdown
- Fully focused on Russia (from Kaliningrad to Kamchatka).
- Real-time data (weather, opening hours) to suggest "Plan B" activities instantly if conditions change.

### Target users
- Regular Travelers (Have already visited popular places (e.g., Sochi, Golden Ring) and want fresh, similar-style destinations)
- Families with kids (Need child-friendly hotels, short travel times, and age-appropriate activities)
- New Travelers (Look for safe, budget-conscious options with social or quiet preferences)
- Busy couples & friends (Want a quick, ready-to-go weekend trip without hours of research)
