The travel style, which takes passengers to a long list of destinations over what is often the course of multiple months, is typically only available on large ocean cruises.

Travelers booking at the base fare on any of Uniworld’s river cruises in Europe will have three daily meals, unlimited alcoholic and non-alcoholic beverages, shore excursions, onboard entertainment, fitness classes and facilities, snacks, 24-hour room service, and more included.

Upgrade options for excursions, spa treatments, celebration packages, and a “Diamond Menu” of non-included wines and spirits are also available at an additional cost.

For the majority of its European cruises, Uniworld directly owns and operates its ships, which are known for their highly individual, boutique design.

The rest of its fleet—the S.S. São Gabriel in Portugal, the S.S. Sphinx and River Tosca in Egypt, the Ganges Voyager II in India, the Aria Amazon in Peru, the Mekong Jewel in Vietnam and Cambodia, and the S.S. Victoria and S.S. Elisabeth in Central Europe—are chartered in partnership with affiliate travel groups.
