“From the dome of St. Peter’s one can see every notable object in Rome… He can see a panorama that is varied, extensive, beautiful to the eye, and more illustrious in history than any other in Europe.” Mark Twain – The Innocents Abroad

Rome is the most important holy city in Christendom and St Peter’s Basilica at the heart of the Vatican City is the headquarters of the Catholic Church and is a place where some of the most important decisions in the history of Europe and the World have been made over the centuries. (A Basilica by the way is a sort of double Cathedral because it has two naves).
Have Bag, Will Travel 
That bottle of water is as expensive as the coffee that you had a day or two ago.
This is all part and parcel of being tourists. As long as you had a good time and everyone enjoyed their day out, that is the main thing.
Thank you for that well written and informative guide..you can write a book about travelling in Europe
