## Prompt

Build a one-day Paris itinerary. Constraints: start 9:00, end by 17:00, must include the Louvre and a 1-hour lunch, no more than 30 min total walking between stops. Present as a timed schedule.

## Response

Here's a focused one-day Paris itinerary maximizing major sites while respecting your time and mobility constraints.

## One-Day Paris Itinerary (9:00–17:00)

| Time | Activity | Duration | Notes |
|------|----------|----------|-------|
| 9:00–9:30 | Travel to Louvre | 30 min | Metro from central hotels (Lines 1, 7, 14) |
| 9:30–12:30 | Louvre Museum | 3 hours | Focus: Mona Lisa, Venus de Milo, Winged Victory. Book timed entry online to skip lines. [Louvre Tickets](https://www.louvre.fr/en/tickets) |
| 12:30–13:30 | Lunch | 1 hour | Café Marly (overlooking courtyard) or nearby bistro in 1st arrondissement |
| 13:30–14:00 | Walk to Arc de Triomphe du Carrousel | 5 min | Iconic photo spot, minimal detour |
| 14:00–15:30 | Tuileries Garden & Champs-Élysées | 1.5 hours | Leisurely stroll, window shopping, rest benches available |
| 15:30–16:00 | Metro to Notre-Dame area | 20 min | External viewing only (under restoration through 2026). Alternative: Sainte-Chapelle (stunning stained glass, 15 min walk) |
| 16:00–16:45 | Sainte-Chapelle OR Île de la Cité walk | 45 min | If Sainte-Chapelle: entry + interior. If walk-only: Seine views, bridges |
| 16:45–17:00 | Return to starting point | 15 min | Metro or taxi |

## Key Optimization Notes

**Why this works for your constraints:**
- Louvre is the centerpiece (3 hours captures essentials without exhaustion)
- All transitions use metro (fast, reliable) or short walks
- Total walking: ~25 minutes
- Built-in buffer time for queues or slower pacing

**Pre-arrival checklist:**
- Book Louvre timed entry 1–2 weeks ahead to avoid 2-hour queues
- Download the [RATP metro app](https://www.ratp.fr/) for real-time transit
- Purchase a carnet (10-pack metro tickets) or 1-day Navigo pass

**Alternative lunch option:** If you prefer sitting down, Ladurée or À Priori Thé near the Louvre offer faster service than full bistros.

**Rainy day pivot:** Extend Louvre to 4 hours, skip outdoor walking, add Musée d'Orsay (impressionist paintings, 20 min metro from Louvre).

Would you prefer recommendations for specific neighborhoods to explore if you return to Paris, or help planning an evening after 17:00?
