Hi, I am going to be in Italy in May and I will be travelling from Florence to Portofino with ItaliaRail. I understand that as of now FFP2 masks need to be worn on interregional trains. We have multiple stops on our route. First we take a train from Florence to Pisa, then Pisa to La Spezia and then La Spezia to Santa Margherita Ligure. Does this mean that we would only need to wear the FFP2 mask on the section from Pisa to La Spezia since that is the only interregional part of the trip? And for the other legs we could wear surgical masks? Also, does anyone know if we need an FFP2 mask to get into museums? Thank you so much for your help!
