The e-voucher provided by the Klook platform cannot be used directly. Please remember to refer to the email sent by the tour operator and go to the designated meeting point at the specified time to check in with the staff. 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 responsible and knowledgeable, providing us with detailed explanations of the historical background 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 must 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 the highest building in Rome, you can overlook the entire city.
