Whether you should carry your physical passport when disembarking at a port of call is a subject of debate, but it is generally recommended for emergency preparedness. Most cruise lines will suggest you only need your "Key to the World" or "SeaPass" card and a government-issued photo ID (like a driver's license) to get back on the ship. However, should you miss the ship's departure or require an emergency medical evacuation, you will be stranded in a foreign country without the legal documentation needed to fly home or cross borders. In 2026, many seasoned travelers choose to carry their physical passport in a secure, waterproof neck wallet or at least have a high-quality color copy and a digital scan on their phone. Some specific countries may actually require a physical passport for entry at the pier, so it is vital to check the daily "Freestyle Daily" or "Compass" newsletter provided by the ship for specific port requirements before you walk down the gangway.
