What is a "Tour Conductor" program and how does it work?

The cruise line will generally provide a complimentary berth (a berth = 1 cruise fare. NOT a cabin) for each 16 full fare passengers travelling together. The value of this berth is returned to the group leader after the group has sailed (in order to account for last minute cancellations). The amount of this Tour Conductor refund is based on the average cost of all staterooms booked for the group.
