I had the privilege of having a private tour at night many years ago after the museum closed at night and I was the only one there just me and my private guide. I was the only person in the Sistine Chapel. I had Michelangelo all to myself and it was so incredible I wanted to fall on the floor and stay there to spend the night gazing up at that magnificent ceiling. There was no one else and it was one of the highlights of my life indeed.
