I am staying at the Hilton Molino Stucky in Venice in late August, and want to get from Venice to Naples (actually final destination is Sorrento, but I will worry about Naples to Sorrento as an aside). I would appreciate opinions on flying vs train.....flight is cheap and short, but I am wondering if I will lose some of the time I save just getting to the airport vs train station. This hotel is on another island, and apparently requires a water taxi or shuttle to get to the main Venice area. Once I make that trip and get to Venice, how hard is it to get to the airport vs the train station? Advice is appreciated.
