We booked a bus tour and tickets for St Peter’s - obtaining the bus ticket was simple but then we were given a hand written note and pointed in the general direction of the office for the rest. After eventually finding the office we were given another hand written note and pointed to the bascillica. No one there had a clue so we just gave up on it - lesson learned.
We arrived to find that this company had much shorter hours than the other tour bus companies from 9:30am -5:30pm. Also the weekend that we were booked an event had them closing at 2pm on Saturday and we had 48 hour tickets from Friday at 4pm to Sunday at 9am, when we were flying home. Since they were going to be closed down, we were given tickets that proved to be utterly useless. There was no skipping the line and the attractions closed when our tickets were timed for?!!! Useless compensation and no notice given of the "special hours" even though we booked well in advance and their closing was annual. We also noted that 2 other bus companies continued running until much later and did not close, but accommodated the routes. Waste of money!!! If you do book a tour, go with someone else for the bus tour. The green bus looked great and ran well into the evening!
The Hop On, Hop Off bus is a great way to get around the Rome city center. Riders are given head phones and allowed to select the language. The audio explains everything you see as the bus makes its way through the city. We also used it to get us closer to our hotel which lies outside the city center. This saved us on taxi fare.
