Venice lockers in railway station
 

We are flying in from Paris so will arrive at the Marco Polo airport and are only wanting to stay in Venice for the day (till about 5-6pm). Where can we leave our luggage for the day- we will be leaving from the railway station, do they have lockers big enough for suitcases?

Train stations do not have lockers; they have manned luggage storage. There's luggage storage at Venezia Santa Lucia train station or at Piazzale Roma, where the buses from Marco Polo end.

This link may help - It has a list (and some pictures) of all the LEFT Luggage counters in train stations in Italy and also has a few other options in Venice (the cruise terminals for example):

thanks so much for that information, it has been a big help
