We are staying in Paris for 5 days and then flying to Venice. It is my understanding that they will not be stamping the passports when we arrive in Venice. We are staying in Italy for 12 days in various Cities, traveling by train. We arranged our accommodations through AirBnB and are paying via credit card. We stay in a couple hotels along the way, but the Venice stay is an AirBnB in the Dorsoduro District. The owner of the unit specifically stated we needed to provide that document. We can message them and see if they can help us out in any way, but am anticipating we might need to do it ourselves and if so how we do that.
