Meet one of the English-speaking staff at the meeting point and they will make sure that you don't go in by yourself. They will bring you to the priority entrance of the Louvre museum so that you can avoid the queue at the normal entrance.
After entering the museum, they will take you directly to the Mona Lisa while giving you some important information about the Louvre. Upon your arrival at the Mona Lisa, you will be able to admire the mystery of da Vinci's masterpiece.
Afterward, you will be able to continue your visit by yourself, at your own pace, and see the thousands of other works of art on display at the Louvre at your own pace.
