Jason-Of-The-Seas

Hi Matt! In late September we'll be sailing on the Quantum of the Seas for our first Alaskan cruise. (Can't wait!) We noticed that we depart from Seattle but disembark in Vancouver. Is there anything special we should have prepared to do or be aware of with us returning to a different country then where we sailed from? Or should we expect the same process and documentation (passports, sea pass card) that we are used to providing for a cruise that starts and ends in the US what will occur here too? Thanks!
