Getting to the Meeting Point:
Vaporetto: line 1, get off at San Marco Vallaresso. Proceed to the end of Calle Vallaresso, turn right and continue walking until you arrive at a colonnade, under which you can find the entrance of Museo Correr
On foot (from Saint Mark's Square): With Piazza San Marco and the arches of Museo Correr at your back and the Poste Italiane (Post Office) in front of you, look on the left and you will see a big grey newsstand (with many souvenir and newspapers): that one is the Venice Tours Assistance Point.
Absolutely loved it
Nice experience to be had as a tourist in Venice. Overrated only due to the crowds. Guide was informative.
