The Turbo Pass sounds good, but is superfluous. At the airport you better take a Vaporetto for 15 € per person and comes over water beautiful in the city, wherever you want, instead of a bus transfer to the bus station. Here you have to go back to the actual destination with a vaporetto or water taxi. The entry into churches was such that we did not get into the top attractions with the turbo pass. Each cost extra.
