Ok, hopefully this suggestion is not too radical but valuable for those living on the eastern side of the continent:
Velo Quebec not only has a great signed bike network in Quebec, but they have organized bike tours overseas for a number of years annually. (Yea, can you imagine a cycling advocacy organization with a business arm like that??)
http://www.explorebybike.com/europe-bike-tour A good friend plans to cycle in Italy with Velo Quebec this summer. She's going to join the tour on her own. She lives in Ontario.
And don't worry, there would be enough people in the group who would know English.
So you would have a real multi-dimensional experience, Italy plus learn fellow cyclists who might be abit different.![]()
