We will be staying in Tessera and traveling back and forth to the city of venice. We planned on getting a venice card but heard you can't use the card on the line 5. Technically we would be using the card to go back and forth from Tessera( one stop prior to the airport) to the Piz. Roma stop. Would we still be able to use the Venice card? We are gettign a really good deal at the Marriott's Courtyard (about 40 euros a night) would this be worth the hassel of commuting back and forth? I know we can find a hotel for that price MAYBE near venice but it would not be anywhere near the same quality.
