My flight is due in at around 20.00 later this week. I've got the bus before but it was years ago and, having had a Google just now, I'm anxious and confused! I will want to use the vaporetti once in Venice itself and in my head there is essentially one bus that sort of meets the planes. But now I'm seeing stuff about different busses, booking in advance etc and I'm losing my nerve. Should I just try and get a taxi - or is that not even an option? Has anyone done this recently who can explain it like I'm five?
