Did you know that you probably don't need a passport to cruise internationally? How does that work? Well, as long as you're on a closed-loop cruise, it's a cruise that starts and ends in a U.S. port, you don't need your passport, usually. You can just take a burst certificate, we actually take photocopies of ours, and a government issued photo ID like your driver's license. We did end up getting passports for our Alaskan cruise, because that's what was advised when we went to Victoria, but our first six cruises we took without passports. Now, don't just take my word for it, be sure and check with your specific cruise line to see what their policies are, and happy cruising!
