Hi Warren,
"RSD" location reviews many times are not done anonymously. There often is a photographer in tow if the writer doesn't do his own work, and sometimes an executive or staffer or two. Occasionally, the writer of an article may have a financial interest in the location, such as is the case with photographer Stephen Frink's several pieces on the Dominican Republic. No doubt that many resorts/dive ops go the extra mile when they know a scuba journalist is present.
My reviews were done as an independent, and I paid my own way. Not sure if other "RSD" writers have received comps, but I wouldn't be surprised if this happened at some level at least occasionally.
BTW, I write many location reviews for "Undercurrent," and a condition of these is anonymity & no comps.
I might also mention that my location reviews for "RSD" were closely edited for any offense they might have given current or potential advertisers. With "Undercurent," this of course is not an issue.
Dive long & prosper.
