It is advisable to arrive earlier than the booked time to facilitate the organization of the group and the security checks. For group tickets for the Basilica, it is advisable to arrive at least 1 hour before the entry time. For the Dome, it is preferable to arrive at least 2.5 hours before, taking into account the visit to the Basilica before accessing the Dome. During the Jubilee, some days may be particularly crowded. It is therefore advisable to arrive earlier, also considering the security checks, to guarantee entry at the scheduled time. Accredited guides will be able to provide further information and useful advice to facilitate entry.
