Check the box. Made it to Venice before it is no longer with us. It won't happen in my lifetime but rising sea level will get this gem at some point. Already many first floors have been abandoned. The famous St Marks square floods quite often.
You cannot get around Venice without taking a boat. Well, you can but who would want to do so. There is a "bus line" running down the Grand Canal, water taxis, gondolas and more. The Amazon packages are delivered by boat. The garbage is collected by boat. The ambulances are boats. The hearses are boats.
Upon arrival we took a water taxi from the train station to our hotel. We rode the Grand Canal "bus". We were on a boat or multiple boats every day. We left Venice on a water taxi to the airport.
