Technically, you can leave a cruise ship at any port, but it is legally and financially complicated. If you choose to "jump ship" early, you must notify the Guest Services desk to avoid a "missing person" emergency search and rescue operation. You will likely be charged a fine (often $800–$900) for violating the Passenger Vessel Services Act (PVSA) if the cruise is a "closed-loop" U.S. itinerary. Furthermore, you are responsible for your own immigration and customs clearance in the foreign country where you disembark, which can be difficult if the country requires a specific entry visa that you don't have. You will not receive a refund for the unused portion of your cruise, and all costs for travel home will be entirely out of your own pocket.
