Louvre's Secret Entrance

There is a "secret" entrance to the Louvre that allows you to bypass the ridiculous line at the public entrance. The Porte des Lions entrance is the best entrance into the Louvre. From this entrance, you can buy your tickets, enter the museum, and have the shortest route to the Italian Renaissance painting section. This door always has the shortest line. Also, if you wanted to see every piece of art in The Louvre in one visit, it would take you over a month, assuming you were there 24/7 and took no breaks or sleep.
