I just booked Louvre Museum tickets on Klook and it's really worth the money, especially for the time savings. Priority tickets mean almost no queuing, just show the QR code and go straight in, avoiding the scene of standing and waiting in the long line of people in front of the museum entrance. Inside, it's super spacious, walking for a few hours still feels not enough, every room has eye-catching masterpieces, from Mona Lisa, Venus de Milo to historical paintings and even the building's architecture is a masterpiece.
My small tip: go in the early morning or evening slots to avoid crowds, and if your main goal is Mona Lisa, choose the package with staff/guide who lead straight to that area for speed, no getting lost in the Louvre "maze". Anyone coming to Paris who likes art, history or simply wants a place to be "wowed" continuously should dedicate half a day to a full day for the Louvre, and remember to book tickets in advance on the app to avoid the hundreds-of-people queuing scene.
