ACTV's Hellovenezia outlets sell vaporetto public transport tickets and passes. If you're lucky, you can also pick up one of the free transport timetable booklets, but these are published at the start of the season and tend to run out swiftly (you can download them at www.hellovenezia.it/orari). Hellovenezia's extremely helpful call centre can provide you with information on ACTV vaporetto and bus schedules, and on events and tourist sights, in English. Hellovenezia shops and booths can be found at the airport and train station, in piazzale Roma and at most vaporetto stops. Outlets at the larger stops (Accademia, Rialto, San Marco Vallaresso, San Zaccaria) sell Venice Card passes; those at the train station, Tronchetto and piazzale Roma also sell tickets for events.
