As a Mexican who has seen our beaches gradually destroyed by endless visiting cruise ships year after year, I feel compelled to remind people how terrible they are for the planet.
Not to mention, they are also super legally sleazy. They are often harboured at countries that have no legal protections. If something happens to you on a cruise ship, it's your own damn problem. Being registered in those tiny corrupt countries also means that they don't have to answer for their ecological destruction.

I wish I could be excited about going to such an event. It seems like it would be super fun. But I don't want my fun to promote such evils. I am very saddened by the coral reef destruction I have witnessed first hand throughout my life.

Best of luck with your cruise conference!
I worked at an agency that did work for pharmaceutical companies and doctors/med salespeople do this all the time! There were a couple of jobs in Punta Cana, DR alone each year.
I must admit that while those cruises were great fun and quite interesting, they showed my wife and me that it's not the kind of vacation or travel that is our style. Lots of other people do enjoy them, though -- and I'm happy to see that someone else is trying this!
The organizer might want to contact the Insight Cruises people; I don't think that they're in direct competition any more, and perhaps they'll have something useful to suggest from their experience.
