What is an easy way to find an international cruise on URComped.com?

The Cruise Search Tool! So if you are logged in, select the tab that says "Tools", and then select "Cruise Search". You can filter by departure port. It could be Rome, Barcelona, Sydney, Singapore, and more. If it's an international departure port, it's more than likely going to be an international cruise. There are transatlantic which can be tricky because they may leave from a domestic port like Miami.
