I too did this ... would not recommend trying to run through the louvre in 1 day. I was kind of "forced" to (only had 1 day and I guess a rare case of FOMO). Spend at least 2-3 days there. It's huge with so much masterpieces. The Mona Lisa was a disappointment.

I imagine the Mona Lisa is fantastic if you get to inspect it in close detail. Trying to poke your head over 100 flustered tourist, through a sea of arms, phones and cameras, is probably not the best way to appreciate it.
