We had breakfast at the hotel and then headed over to Vatican City on the Metro (hugging our possessions tightly).
I had tried to make the faxed reservations for the Vatican Museum-Sistine Chapel tour where you go in the back door and do not have to stand in line, but heard nothing before we left home, so we decided to take our chances. The line was HUGE! A guy came up trying to sell us a tour and bypass the line for 50E each (including the 12E entrance fee). The tour guide supposedly spoke English, but we could barely understand her, so we left the group once we got inside.
Too many people all the way thru the Museum and the Sistine Chapel until we got to St. Peter's Basilica. Its so huge that we were no longer crowded. And gorgeous - you just cannot imagine how gorgeous it was!
