We just arrived in Venice last night. November 1 is All Saints Day and many sights will be closed. Any suggestions for the day?
All the museums will be open, just avoid an islands tour or grand Canal tour with public transportation ( vaporetto) as there will be very long queue everywhere and they will be overcrowded.
Walk in most any direction away from the crowds. Then just stroll, and stroll. Before you know it, you will be in areas almost by yourself. Then you can experience the real Venice sights and restaurants.
