All of the pieces listed in the tour description are viewable the vast majority of the time. However, the Met, like nearly all great museums, occasionally allows certain works to travel in temporary exhibitions or be lent to other institutions. The Met also allows private parties to book out certain rooms for events (most commonly the Temple of Dendur), rendering them inaccessible for the duration of the event. If one of the listed pieces is unable to be viewed, the guide, at their discretion, will substitute another piece of important value.
