If you’ve ever gasped while checking the prices of European river cruises, you’ll exhale with glee when you see the itineraries offered by Teeming River Cruises. Launched in July 2017 by Florida-based husband-and-wife entrepreneurs Jeff and Gina Paglialonga, Teeming turns the traditional river cruise formula on its head — and offers fares that are 50-65 percent below average — by breaking from all-inclusive pricing and going back to basics: a comfortable cabin and three well-prepared (albeit not gourmet) meals daily, plus afternoon tea. That’s it. No included shore excursions (there’s an app for that), no open bar, and very little in the way of pampering. But in doing so, Teeming is creating a new strata of river cruising geared to low-maintenance, highly independent travelers.
