We traveled to the airport via Alilaguna two years ago. My son is special needs, in a stroller, and I didnāt want the hassle of multiple transfers via vaporetto/land bus with him and our luggage, and I felt that boarding a water taxi might be tricky.
I will note that we had (effortlessly) taken countless vaporetto trips during the week we were in Venice, but the combination of the luggage, stroller, and land bus transfer made me twitch.
The Alilaguna was fine. We wheeled my son and our luggage right into the boat and sat below. We were able to store the luggage behind our seat. The ride to the airport was hassle-free and seamless, no stress.
It wasnāt scenic, but it got the job done. Iād make the same choice, for us, next time.
Iād also add that if I werenāt accommodating mobility issues, Iād choose the water taxi every time. Flight days are too crazy; I always opt for the easiest transfer option to/from airports. And it is so much nicer being on the water than a land bus!!!
