I think that I got lucky in that when I visit next month, since it is midweek, there is only 1 large ship in port although if it was two days earlier, it was a lot more.
Someone told me about the documentary Venice Syndrome. I am afraid to watch it before our trip.
My wife already feels bad that she is visiting and potentially part of the problem although we are actually spending money in a hotel and will be going to restaurants for dinner...settled on Corte Sconta and Osteria Oliva Nera the second night of our trip...
