Book a ticket that allows for unrestricted use of public transportation services in: the city of Venice; Lido and Murano; and Burano and Torcello island. Also ride the land buses in Mestre and Marghera.
Enjoy your trip in Venice and use public transportation without queuing at the ticket offices.
Just head to the yellow ticket machines that you can find at the vaporetto stops across the city: enter the PNR code that you'll find on your voucher and get the paper ticket with which you can catch your vaporetto.
Your tickets must be validated each time before boarding a water bus. The validity of your ticket begins from the exact time it is first validated.
