In 2026, a 60-day "Grand Voyage" or partial World Cruise typically costs between $12,000 and $45,000 per person, depending heavily on the cruise line's luxury tier. For "mainstream" lines like Princess or Holland America, you can find 60-day segments for approximately $200–$300 per day, totaling around $15,000 for an inside cabin. On ultra-luxury lines like Viking or Regent Seven Seas, prices can soar to $65,000+, though these often include business-class airfare, shore excursions, and laundry. For 2026 travelers, "Grand Voyages" are considered the best value for long-term travel because the price covers all meals, entertainment, and transportation between dozens of international ports. If you book well in advance (12–18 months), you can often secure "Early Booking" discounts or significant shipboard credit, which helps offset the high upfront cost of such a lengthy maritime adventure.
