The meeting point with the guide is very well indicated. She showed us where to enter. Once inside, the security check is quick, and you're already in the gallery. The audio guide takes a little while to understand, but once you get the hang of it and get used to it, you can explore on your own. It's well explained in the selected language. You have unlimited time to view the artworks and stay in the museum. A great experience.
Got there in my time slot, was given printed out skip the line tickets, and walked to the start of the line by a guide. Went straight into the gallery. Really worth it!!!
