I sw Steven Stern on Oasis. There is another new poster here who likes Stern as well.
It should be noted that Stern does attend complimentary cruises as well. I have no knowledge if that's acknowledged in his guides, or not.
[ed note - we have to be careful to say that we also don't know if he uses those "fam cruises" to shape his reviews. He could go back on the ships on his own later on a regular passenger cruise.
I can tell you that back in the day of Anne Campbell writing Fielding's Guide (1993) she had a rule that no ship was reviewed until it had been in service for 6 months and she could take a full, regular passenger cruise. However, back then there were about 80% fewer ships in service. - Paul Motter]
