If you visit the Vatican, make sure you give yourself a day to do enjoy it, not just a few hours.
We bought our tickets on line early for early admission with breakfast. Worth the few extra bucks. Even late November, a crowd was developing quickly. So we were glad to have the early admission tickets, especially since in was cold outside. By the time Breakfast was over, the weather warmed up a bit.
Breakfast was a plentiful buffet and they allowed all the time you needed. Coffee; tea & juice were included.
We did not due a tour, because we wanted to take out time and go at own pace, but we heard other tours that sounded quite interesting and informative even while we were waiting in line outside. They also had audio tours for those wanting to go on you own, which seemed like a good idea, except it seemed everyone with the audio tours had to stop right infront of everything while they listened... so standing in the way of others wanting to view or take pictures.
The museum is huge, so don’t expect to walk through in just a few hours, plan a day.
There are restaurants; cafes & a pizzeria inside, so you don’t have to leave for lunch.
Children and teenagers get a discount.
