There are at least two companies that have them. The reports are upwards of 50 pages of narrative. Worth it for a 10-day balcony cruise. Not so much for a 7-day inside cabin to a destination you've been to several times.
You need to fit the demographic they're after. That could be "first-time cruiser," ethnic minority of one flavor or another, lifestyle choice, over 60, live near a cruise port, tiered membership in a cruise line, etc (even all of the above!) Make certain you're filling out the sections on MSC sites that are asking for these.
