We are arriving in Venice on Thursday for 5 nights (family of 4 adults) and I wondered whether we are best buying a vaporetto ticket for 5 days, also where do we purchase these? I'm sure that all this information is available in the threads but have left it rather late to browse. Also, we are staying in Siestiere Castello and would like to visit some restaurants where the locals go - are there any suggestions? We were in Venice some 12 years ago and found these restaurants so nice but unfortunately, I do not remember any. Any advice would be greatly appreciated.
