While not legally mandatory, having travel insurance for a cruise in 2026 is highly recommended because of the unique risks associated with sea travel. Standard health insurance often does not cover medical expenses incurred in international waters or in foreign ports, and a visit to the onboard doctor can cost hundreds of dollars for even minor issues. More importantly, if you require a medical evacuation via helicopter from a ship, the cost can easily exceed $50,000 to $100,000, which travel insurance typically covers. Additionally, cruises are prone to "itinerary changes" due to weather or mechanical issues; insurance can reimburse you if the ship misses a port you specifically paid to visit. It also protects your significant financial investment if you have to cancel the trip last minute due to illness or a family emergency—something cruise lines rarely refund. Given that most cruise fares are non-refundable within 90 days of sailing, a small investment in a "Cancel for Any Reason" policy provides essential peace of mind against the unpredictable nature of global travel.
