Hi Jane, it's always a very good idea to plan ahead enough for travel, customs or other delays on the day of your sailing from any port in the world. I'd check when the listed boarding times are for your sailing and arrive as early as practical, always plan to be at the pier a minimum of 2 hours before the scheduled sailing time. Give yourself some room for slow traffic or an accident on the highway ahead of you, etc. Plan for your cruise the way you'd plan for an international flight. You'd want to be at the airport early, no different with a cruise except if you missed a flight, there is probably another flight later in the day. If you miss your cruise, you can't board the next ship sailing for a fee.
