Taxes I love Italy. But, if Venice imposes toilet taxes or a charge of one cent to enter San Marco I promise that no member of my family will set foot in that city. A charge to use the facilities is fair. Upkeep is necessary. However admission to the public areas is outright theft.
Tourists spend a fortune every summer in Italy.
If Italy is going to play this game they may find that Americans may prefer the rude French to the now wonderful Italians. Don't kill the golden goose, Venice.
