## 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

This plan keeps everything inside a compact Louvre–Île de la Cité corridor, so total walking between stops is about 30 minutes. It front-loads the Louvre (least crowded right at opening), places lunch on Île de la Cité, and finishes with Notre-Dame and Île Saint-Louis. Avoid Tuesday: the Louvre is closed that day.

## Booking Essentials

Book all three timed entries the moment your date is fixed; same-day availability is unreliable in peak season.

**Louvre**
Timed-entry tickets; 9:00 slot recommended, closed Tuesdays
Buy: https://www.louvre.fr/en/visit

**Sainte-Chapelle**
Combined ticket with the Conciergerie available if you want a swap option
Buy: https://www.sainte-chapelle.fr/en

**Notre-Dame de Paris**
Free entry; reserve a free timed slot to bypass the standby line

## Adjustments

- **Running late at the Louvre:** cut Sainte-Chapelle and lunch at 12:30 instead; walking drops to about 25 minutes.
- **Rain:** replace Île Saint-Louis with the Conciergerie (2 min from Sainte-Chapelle), keeping walking near 20 minutes.
- **Mobility concerns:** the Pont Neuf leg is the longest; a single Métro hop (Louvre-Rivoli to Cité, Line 1 then 4) cuts it to roughly 5 minutes of walking.
- Confirm opening hours the week of your visit, since seasonal and holiday schedules shift.

Would you like a version optimized for a specific season or with a Left Bank alternative instead of Île Saint-Louis?
