In Paris, many museums are free on the first Sunday of each month. Thus the lines for museum entry can be extremely long. Is it possible to skip through the line if I bought a ticket in advance?
I ask because the security line to enter the Louvre is usually quite long and visitors who pre-purchased tickets can skip to the front of the security line, so I'm wondering if this applies on free-entry days (as it can be worth my money to save time in the line).
