The Viking Astrea launched at Fincantieri's Ancona yard running partly on liquid hydrogen and fuel cells — a setup whose only tailpipe byproduct is water on the stretches it powers. It's the second hydrogen-capable Viking ship in the water this year, and that zero-emission capability is exactly what could keep the best fjord itineraries open as emissions rules tighten. Maiden voyage: June 2027.

Packing for kids is a different game. Our family-edition list runs age band by age band — two swimsuits per kid, lanyards, sand toys, a stocked first-aid kit, documents, and the cabin sanity-savers experienced cruise parents never sail without.

The advertised fare is only the start. We break down base fares by line, then add the real-world costs — gratuities, drink packages, Wi-Fi, and excursions — so you can see your true all-in total before you book.
