If you miss your cruise ship at a port of call, the first thing you must do is contact the Port Agent. Their contact information is always listed in the "Daily Newsletter" or the cruise app; they are the shoreside liaison between you and the ship. If you left your passport in your stateroom safe, the ship's security team will often leave it with the Port Agent before they depart. Your next step is to arrange your own transportation to the next port of call at your own expense. This can be a high-value "nightmare" involving last-minute flights and emergency visas. Most standard cruise contracts explicitly state that the ship will not wait for "independent" travelers, only those on official ship-sponsored excursions. A peer-to-peer essential is to always carry a credit card and a photo of your passport when you go ashore. If you have Travel Insurance with "Trip Interruption" coverage, they may reimburse you for the costs of catching up to the ship, but without it, the financial burden of "pier-running" failure falls entirely on your shoulders.
