One new regulation requires all large groups touring the basilica to wear headsets while the guide speaks into a microphone. In the inevitable chaos surrounding the implementation of a new policy, several astonished tourists have seen their guide forbidden to speak in the absence of the so-called whisper sets. The sets are available for rental at the entrance to the basilica, but one should reserve ahead as they tend to be always taken.

The custodians are also strictly enforcing a no-tour rule from 4:30 p.m. on. Whisper set or no, large groups cannot tour the basilica as the sacristans are preparing for the 5 p.m. Mass.
