Remember to budget for shore excursion expenses. Excursion prices can vary greatly depending on your port of call, cruise line and activity.
You're never obligated to take an organized shore excursion. To explore a city more in depth or see something not included on an organized excursion, consider exploring on your own.
During a shore excursion, always carry identification, the name of your ship and its docked location. Bring a photocopy of your passport with you as well.
Leave valuables, excess cash and unneeded credit cards aboard while on shore excursions.
