Is there a vaporetto that will get me from San Marco to Marco Polo Airport early enough for a 7:10 a.m. flight?
Carol, no vaporetto goes to the airport. But, the Alilaguna boat (www.alilaguna.it) does have runs from limited stops in Venice that do go to the airport. The Linea Blu boat stops at San Marco and San Zaccaria at 3:40/3:44 and 4:50/4:54. These two runs arrive at the airport at 5:00am and 6:07am respectively. Fare is about 15Euro.
