The Wikivoyage article on the Wagah/Wagha "Beating Retreat" ceremony mentions that I can take Minibus No. 4 from Lahore to the Pakistani side of the border, but the section on how to get seated for the actual event only seems to cover what to do on the Indian side. It does mention that the Pakistani side draws a smaller crowd.
An existing question on this site covers the Indian side.
If I want to see the border ceremony from the Pakistani side as a foreigner, is it acceptable to simply show up before the ceremony, or do I need to do anything, such as buy a ticket or obtain travel clearance?
To be clear, my nationality does require a visa to enter Pakistan, but that is not part of the question. Assuming that I have (or can obtain) the proper visa, can I simply travel from Lahore straight to the border and expect to be seated as a spectator?
I'm not asking about how to cross the border there, only view the border ceremony.
