The Vatican (including St Peters) An Audience With His Holiness
This review is especially helpful for those who have or use the following: Wheelchair
Two major things I would point out here - follow the signs (English & Italian) and obey the rules (dress code, no photos) - you can't go far wrong! Have your passport handy for admittance to the museum.
Transport & Parking
I would strongly advise going on foot - as I did.
Getting around St Peter's Square is easy as it is on the flat - but when we saw The Pope, there were crowds to be negotiated. It's basically find a space! Entry into The Vatican Museum is via a lift then there is a long walk through several galleries filled with awesome treasures to The Cistine Chapel (there is a stairlift), which is packed with people. There is a lift up to The Basilica & a ramp into it.
There are various toilets dotted around The Vatican - just ask.
Variable - ranging from the helpful to the offhand. (But they all speak English.)
Anything else you wish to tell us?
For sheer interest sake - even if you're not particularly religious, it is well worth a visit.
