I want to buy online the tickets for transportation in Venice. I'll be there for 3 days + airport transfer. My hotel is near Rialto and for departure I would like to ask your advice. My flight is at 9.25 AM to Amsterdam- I saw that Alilaguna has a waterbus at 7:06 and I get to airport at 8 which sounds good to me. I read somewhere here that this service is a shared launch, therefore a minimum of 2 passengers are required and the launch may wait for as much as 40 minutes to fill up. In that case wouldn't be better to take the bus #5? Please advise.
