I am helping a friend with Rome plans. I have seen several mentions of the exit out of Sistine Chapel to the Basilica. When I was there a few years ago, we did the museum tour. The tour ended by leaving you at the chapel. We were not permitted to exit to the basilica and had to walk around and enter through St Peter's Square. Has something changed? or must you book the museum and St Peter's tour for access to this route?
Thank you for any help.
