Yes, once a cruise ship has been "cleared" by local customs and immigration authorities at a port of call, passengers are free to get on and off the ship as many times as they like during the scheduled docking window. In 2026, this process is highly streamlined; you simply scan your digital cruise pass or "wearable" medallion at the gangway. It is important to note the "All Aboard" time, which is typically 30 minutes to an hour before the actual departure time. If you miss this, the ship will leave without you. You do not need to be on an official shore excursion to leave the ship; you can walk off to explore the town, return to the ship for lunch to save money, and then head back out for more sightseeing in the afternoon. However, you must always carry your ship ID and a government-issued photo ID (or a copy of your passport) to clear the port security checkpoints upon your return.
