Is there a luggage storage at the train station itself - I see adds for stowyourbags.com 3 minutes from the station. Also for tomorrow do you think I need to reserve a locker? Thanks
Yes. There is a luggage storage at Venezia Santa Lucia station. It's managed by the Kipoint company.
Luggage storage at Venezia SL is about half way down Platform 1. Look for the suitcase sign.
