Hi, everyone-
We are on the Zuiderdam July 7 but are arriving in Venice on the 6th and staying in an airport hotel. Any suggestions on how to transfer to the ship from the hotel and back to the airport after the cruise would be greatly appreciated. Thanks in advance for any help!

You could take a land taxi from the hotel to port,

On return a land taxi or take the #5 bus from P.Roma to the airport it is less than 30 minutes & 3 Euro pp or a water taxi which is pricey
