A few venues in Italy (e.g., Colosseum, Galleria dell'Accademia in Florence, etc.), according to Rick, do not allow "large backpacks" and some have no means of checking bags. How big are we talking? For instance, would the day bags Rick sells on this site pass muster or are they too large as well? If so, does anyone have a sense of what dimensions are permitted?
We have a 1 1/2 year-old and some items are essential to have with us at all times, needless to say.
Thanks in advance!
