Why Choose a 180-day cruise?
A 180-day cruise is ideal for traveling because you do not have to keep checking in and out of hotels over and over again. These long itineraries are aimed at including several ports of call, stunning landscapes, and culturally rich environments. Going on a 180-day cruise is beneficial because there is no need to plan several trips, find a place to stay, and figure out how to get there. The beauty is that you can relax and watch the world go by as the ship takes you smoothly from one port to another.
They can offer luxurious services, spacious rooms, and balconies with stunning sea views, exquisite food, beautiful performances, and a wide range of amenities and facilities, including fitness centers, spas, exciting programs, and more. A 180-day cruise means dedicated workers and staff will organize every aspect of your holiday.
The Cost of a 180-Day Cruise
The price of a 180-day cruise can vary significantly depending on factors such as the cruise line, ship, itinerary, and cabin type. As of 2026, the cost typically ranges from $55,000* to $220,000* per person. This price includes accommodation, meals, entertainment, and access to onboard amenities. Some cruise lines may also include complimentary excursions, while others offer optional shore excursions at an additional cost.
Top Cruise Lines Offering 180-Day Cruises in 2026
Six cruise lines dominate the long-world-cruise market, though only three (Oceania, Viking, Regent) consistently offer voyages at or above a full 180 days. Cunard and Holland America run shorter "Grand" world voyages (100–130 days), and Silversea's world cruise typically runs 130–150 days — we've included them because they compete for the same traveler and because full-length 180-day segments are sometimes available.

What's included:
- Accommodation for duration
- All main meals and entertainment

Not included (typical add-ons):
