I was shocked that there where not many people in the Ancient Mesopotamia part of the museum.
Also almost nobody looking for the oldest written legal document in the East, the Hammurabi code.
I have some advice for the people arriving with a ticket and a time slot. Enter the museum directly from the metro station, there is an entrance there, just find it in the maps.
You don't have to wait a while in the lines in front of the pyramid, just take a walk from the metro directly below the pyramid and have your ticket scanned.
You can buy all your souvenirs there, since they have regular shops with clothes and everything, I especially liked Pylones!
