Most Dutch river cruises run the Amsterdam-Brugge corridor. Uniworld’s Netherlands route deliberately skips it, hitting the less-cruise-served towns the painters actually came from — Nuenen (where Van Gogh painted The Potato Eaters), Delft (Vermeer), Haarlem (Frans Hals). Onboard programming pairs each stop with the museum in the town. Slower than a tour-bus, deeper than a city break.
