The museum has incredible collection of art, no doubts here. But unfortunately the visit process is managed extremely poorly.

1. There is 30C-35C inside, no a/c in 99% of the area. I saw several people getting sick because of overheating.
2. The layout they came with is probably based of labyrinth of minotaur. The put the ropes the way you have to go through all the hyperlong overheated maze without posibility to take shortcut to what you prefer to see more.
3. The maps provided are useless (both paper and online) as the made more like a leaflet showing museum rooms in chaotic sequence. If you use it, you will get lost even faster.
4. Sestine Chappel is an amazine masterpiece, but unfortunately it is agressively used by museum as a marketing product. You will see at each pointer that there are just 2 rooms more to the chappel. Then 2 more, and more, and more. They put it at the end of each pointer, like a carrot for donkey to move forward with a maze of heat. It is located in the end, the last, after hours of wandering, number of stairs up and down. Then you get to the chappel, where you are either forced to move further to the exit or to stand sticked to the crowd, as there is no place to walk and look, everyone is pressed together like sardines in a can. And you can't film and take pics there so other people will go to the maze and marketing will roll.
5. There is no accessibility if you are a parent with a stroller. Some staff gives you shortcut, but mostly you follow the maze and carry your stroller with stairs in 30+ heat. After you got to the exhibition rooms there are no elevators or escalators or they are not accompanied with staff, so you can't use it. Accessibility map they advertise is a lie. Now here are the tips:
6. If you can't hold on with such heat, make a personal must see list must-see.
7. Ask staff along the way how to get to your next point or take an audioguide, looks like it goes in a correct sequence.
8. If you see another room with people behind the rope and sign/pointer to your point of interest, ask to let you through as you are exhausted and overheated. If there is no staff, just pass the rope (if there are other tourists behind it of course).
9. If you took a stroller, you have even more ground to do that. Also insist to a staff member to provide you an elevator to the floor when you are near egypt/hercules sections.
10. To get to Sestine Chappel immediately, from main itersection where you have greek section to your right, pinecone yard to your left, follow to the pine yard and turn right last moment before the door to the yeard. There you will see a back side of stairs, ropes, a staff member and a long corridor behind. Do what is explained at advise 3 above, insist to pass, it is a direct short corridor to the chappel where all the wheelchair and eldery people are led to.

Again, the museum has really unique and beautiful collection, everyone will find something to be amazed, but it is managed with disrespect to the guests, although most of the staff along the maze is friendly and helpful.
