As an alternative to flying, I'm considering to cruise from the east coast of Australia or somewhere in New Zealand to anywhere in North America.
The dates are flexible, but my preference is to depart in December 2016 or January 2017 and routes with island stops are superior.
Most cruise line sites are pretty bad for searching and they don't really have an easy way to search for just ocean crossing cruises and each line is a bit different.
Is there a directory, list, or other way to search all cruises departing around those dates across all cruise lines?
