To do this museum justice, you should plan to spend 2-3 hours here. That means you will be on your feet for a long time: walking, standing, climbing stairs. Make sure to wear comfortable, supportive shoes.
Expect to check any bags you happen to be carrying. The bag check room is located on the ground floor, at the back of the lobby. This service is safe and free.
At the present time, photos and video are not allowed in any part of the museum. I have been at the museum when they were allowing photos on the top floor, but this is inconsistent. You need to ask one of the numerous “hosts” (available on each floor) about the photo policy at the time of your visit.
The facilities are state of the art, with plenty of restrooms and a grand café where weary visitors can rest their feet and relax with a coffee. The prices are high, but not exorbitant. The second-floor bookstore has an excellent selection of books on the Acropolis and its buildings. There is even a guide book to the museum itself that comes in two flavors: short or long.
