The Rates of Gondolas in Venice
The rates of the gondoliers are available on their official site: http://www.gondolavenezia.it/history_tariffe.asp?Pag=43
During the daytime, prices begin at 80-Euros base price for 40 minutes for a maximum of 6 persons and 40 Euros for each additional 20 minutes.
At night the rate increases to 100 Euros for 40 minutes and 50 Euros for each additional 20 minutes. The rate of the possible singers is additional and must be negotiated.
I will publish a video soon of a man standing on the front of a Gondola singing, with a man playing the accordion.
