We thought we were being smart by planning on hitting the Vatican City on Monday. Turns out Mondays are the busiest day of the week because most Italian museums and sights are closed on Mondays. We decided to be part of a tour so we could skip the two hour long line and the complex is so vast that it was nice to have someone navigate us through the labyrinth. I did learn to not believe the salesmen when they are telling you how many people will be in your group. We were told there would be 25 but in the end had about 48 people on our tour.
