@PadreSJ we won't have transportation. We're basically going to be dropped in the middle of the city and left alone for 9 hours. The Sistine Chapel is probably at the top of our list. We are there as part of a Mediterranean Cruise. Despite getting up shortly after midnight to try to sign up for the Vatican tour, it was already full so we are on our own. I guess my question to you is if we are in the vicinity of the Vatican and want to see only two or three things would be your recommendation?
