Best Cruise Lines for Extended European Voyages, Expert Picks 2026

Extended European itineraries (10–21+ nights) are built for deeper travel: more ports, longer calls, and strategic overnights that reward curiosity and stamina. On voyages this long, ship choice matters—mass‑market lines win on price and family features, premium lines add comfort and cuisine, and luxury lines minimize friction with broader inclusions. According to a Consumer Reports analysis of nearly 19,000 members, the typical price paid for a cruise is just over $2,750 per adult, a baseline that rises for longer Europe routes and higher tiers.
