Yes, buying cruise-specific travel insurance is widely considered a high-value necessity in 2026. Standard health insurance, including Medicare, rarely covers medical care in international waters or foreign ports, where a single onboard clinic visit can cost hundreds of dollars and a medical evacuation via helicopter can exceed $100,000. Beyond health, cruise insurance protects against "Missed Connections," which is vital if a flight delay causes you to miss the ship's departure. In 2026, with cruise costs averaging nearly $8,000 per booking, spending 5–10% on a policy provides a safety net for "Trip Cancellation" due to illness or weather. A "pro-tip" is to buy third-party insurance rather than the cruise line's own plan, as third-party policies typically offer higher medical limits and cash reimbursements instead of just "future cruise credits."
