If a papal event is central to the trip, verify the official calendar before committing. The General Audience is held on Wednesdays at about 9:00–9:30 a.m. with free tickets from the Prefecture of the Papal Household, but it is not held when the Pope is away, including parts of July, and St. Peter’s closes to visitors during papal ceremonies. A Wednesday in Rome does not by itself guarantee attendance at an audience.
