If your Mediterranean cruise begins or ends in the busy port of Ravenna, you may want to extend your trip to include Venice. The storybook floating city is a must-see for an Italian vacation—but you may find yourself lost when it comes to how to tie the two parts of your trip together. Ravenna transfers solve the problem. An experienced driver will shuttle you to Venice (or the city’s Marco Polo Airport). Just know that there are no cars allowed on the islands themselves, and you’ll have to find a water taxi to bridge the last mile—which is, of course, part of the fun.
