We are planning to make a short stop at the Vatican, we will be travelling with our 8 month old therefore not planning to see museum as it will be too crowded and we have been there before. My parents will be accompanying us, they have never been to the Vatican and the idea is to just see the Basilica and the main square. Our two options are on a Saturday on a Sunday. Sunday afternoon fits better in our travel plans, but was wondering about crowds and logistics because of the Sunday papal mass. Does anyone have any experience of this?
