Does the PNR work like a multiservice card?

No, it doesn’t. You buy your tickets according to your actual requirements and interests. To access the Venice City Museums and to use the public transport services, the public toilets, the municipal car park and the Wi-Fi network you must have the specific ticket for each service, that you will have purchased by adding each one of them to your personal shopping cart: ACTV public transport card, Alilaguna transport ticket, Terminal Fusina transport ticket, public toilet card, City Museum pass, Wi-Fi network subscription. With the same purchase order – a single PNR – you can buy the tickets for yourself and for your fellow travellers, even for large groups.
