There are specific days each week when you can enter a museum’s permanent exhibit without having to pay for your ticket. Free days are often very popular and each museum handles ticketing differently. So check the museum’s website in advance to see if you need to just queue up early to get a ticket, or prebook in advance. For example, Schindler’s Factory does not allow you to prebook- so you should get in line before they open at 10am to make sure you get inside.
