The only time I had ever been to Venice was over a lovely weekend in October of maybe 1998 or so. Well Venice looks the same, but it was hot and humid. We had had plans to walk like fiends and really explore nooks and crannies. Instead we were in search of shade, breezes, and air conditioning.
While we were in Venice there was a protest against all the big passenger ships that come into port. There are a whole slew of reasons to be opposed to the number, size, and location of ships that call. Many cruise lines start and end Adriatic cruises in Venice, often staying in port over night so guests have an overnight in the city. From my observation, at any given time there are about 5 to 7 ships in port at once at the main cruise terminal. Our ship, not strictly a cruise ship, is about half the size of most of those and has a fraction of the passengers. When we were on there were only about 250 passengers on board as opposed to about 3,000 for the typical cruises that come through. Still it is big. Venice should probably make some decisions about where and how ships access the city, but for now, you come and go right past San Marco. It’s pretty spectacular.
