I learned of a lady who does after-hours tours of the Vatican Museum and Sistene Chapel. Before sharing with you all, I selfishly tried to get a place in her line but it's not to be. She currently does not have any tours scheduled when I will be in Rome. I am so disappointed. However, I'm thinking if there's enough interest she may open a tour during that time. So I will give her web site on this forum, hopefully drum up some business for her thereby creating an opportunity for me. See how this works!
It really sounds like an awesome opportunity. Can you imagine visiting the Sistene Chapel in relative solitude? The cost is 175 E pp for a 2 hour guided tour.
