On November 2nd, the Louvre closed for two hours, reopening at 11:00 AM. My reservation was for 10:30. I spent three hours just browsing the exhibition area, and even with a map and audio guide, I still got lost and kept going back and forth. It truly is a maze. However, it's definitely worth spending more time in the Denon Hall on the first floor, where paintings by Lisa and others are displayed. An audio guide is essential; otherwise, you won't understand anything. You can rent one on-site for 6 euros.
