This is an OBC offered by Carnival. It is the Average of the cost of the cabins of the rest of the group. We are getting an OBC from Canival for the rate code we booked under ($50 per cabin), OBC from carnival for a perk of being in the group ($50 per cabin), then the person in charge of the group gets a rather substantial OBC for organizing the group. (Hundreds of dollars)
The $50 we get from the rate code is already available, the next $50 and the Tour Conductor credit will be along at some point, just not sure when.
