I think it is if you plan a pre- or post-stay in Venice. I'm with Jim Avery - one of my favorite memories is arriving at the airport and taking a water taxi to our hotel. It felt like something out of a movie. We stay at the Hilton on Giudecca to minimize the time we spend getting to Venice via bus or boat - it can be 60-90 minutes each way. Another favorite memory is leaning out our canal-side room's window and taking in Venice in it's totality. We're booked there again prior to our upcoming October cruise. The sail-away out of the Ventian lagoon into the Adriatic is lovely.
