I'm planning for my trip in September and looking to visit the Vatican Museums and St Peter's Basilica. The regular tickets are mostly sold out except late afternoon tix. The "Vatican Museums - Guided Tours for Individuals Museums" are still available. If I purchase these guided tours, can we use the entrance after Sistine Chapel that goes directly to St Peter's Basilica? I don't want to purchase third party tickets.
