No city out-earns its descriptions like Venice still does: palaces on a hundred islands, streets of water — a wonder crowds cannot dull. San Marco (Europe's finest salon), the full vaporetto line 1 palace cruise, the €1 traghetto gondola trick, and rainbow Burano. Sleep at least one night — the city transforms when day-trippers leave; day-visitor fees apply on peak days but overnight guests are exempt; getting lost is half the point.
