Is This the Right Trip Length?
The 180-day full world cruise represents the pinnacle of ocean travel, a complete circumnavigation of Earth that visits every inhabited continent over six months at sea. This ultimate voyage attracts travelers for whom cruising has become a lifestyle rather than vacation, offering the profound experience of watching seasons change while crossing every major ocean and time zone.
