We're about 3 months from our trip to Rome and Florence and we're nailing down the reservations on all the major sites now. There are several locations that are on our itinerary, however, that may or may not require advanced ticket purchases based on how heavily they're visited.
I definitely want advanced tickets to avoid standing in lines, but I think some places may not really justify them and buying at the door offers more flexibility.
Looking at the list below, do you see any places that we should buy tickets in advance for?
