I find it strange that some people are saying they actually needed ID at any port. In the past six months, we've sailed to Iceland, Greenland, Australia, New Zealand, various South Pacific Islands, and multiple South American countries, and not once did anyone ask for a picture ID of any kind. All they ever wanted to see when we entered the port were our cruise cards. In fact, in Valparaiso, we didn't even need those to get back on the ship on turnaround day of a back-to-back.
