The electronic voucher provided by the Klook platform cannot be used directly. Please remember to report to the staff at the designated meeting point mentioned in the email sent by the organizer at the specified time. After checking in, the tour guide will distribute tickets and audio guides to the group members (please keep your tickets safe, as they will be checked at least twice after entering the Vatican). Our tour guide was very dedicated and knowledgeable, providing us with detailed explanations of the history and interesting facts about the Vatican and its architecture, which was very enriching. Please note that once you leave a building within the Vatican, you cannot re-enter it. If you wish to visit again, you will need to purchase another ticket (for example, once you leave the museum for the chapel, you cannot return to the museum). Also, this tour does not include Raphael's Rooms. Tickets to climb the dome need to be purchased separately. The dome has two levels: the first level has 300 steps (with an elevator), and the second level to the very top has 200 steps (no elevator). From there, you can overlook the entire city from Rome's tallest building.
