Hello. I am a bit confused as to how to use the transportation in Venice. Our ship Brillance of the Sea does a 2 day stop in Venice. We arrive at the Stazione Marittima. We want to go to San Marco. Do we need to use a shuttle? Can we walk? Do we need to buy a "one day travel card" or a 1-3 day blu card? We plan to visit Venice, have supper on the ship then go back to town for the evening. Then go again to town the next day for part of the day.
All information that you think we need will be extremely useful. Thanks a lot! :-)
