Entrance Tickets
If you plan to visit several museums during your stay in Venice, purchasing a pass may be the most convenient choice. Venice’s official tourist card is the City Pass Venezia Unica which, in the standard version, includes eight visits (to which you can add more).
You might as well want to consider the Museum Pass, especially if you plan to return to Venice within six months. The combined ticket includes all the museums of Piazza San Marco and eight other civic museums.
