Endless, magnificent, and impossible to 'do' in a day. The fit call is which wing to surrender to, not whether to 'see it all': Denon for the marquee hits (Mona Lisa scrum, Italian painting, the Winged Victory) if it's your only visit; Richelieu's French painting and the calm Cour Marly sculpture courts if you want masterpieces nearly alone; the Egyptian and Near Eastern antiquities in Sully if you've got kids who'd rather have mummies than Madonnas. Pick one, enter via the Carrousel, go at a late opening, and the crowds melt ten metres past the Joconde.
