River cruising for 21-to-45-year-olds: Expect yoga, wine classes and DJs

If your passport lists your age as 46 or older, forget about setting sail on U by Uniworld, a new river cruise company that’s targeting millennials.

Uniworld, which has marketed its European river cruises to multi-generational customers for decades, is moving into uncharted waters with its new “21 to 45 only” cruises.

The company calls U “a new take on experiential travel, with cruises designed for those with a passion for exploring and a taste for authentic adventures.”

Its first cruise, earlier in October made its maiden journey along Paris’ Seine River. Two ships are scheduled to sail in Europe beginning in April 2018, and one ship will sail on the Mekong River in Southeast Asia in 2018.
