Jamaica’s cruise numbers saw solid growth last year, but tourism authorities there are not pleased with the level of per-passenger spending, which trails most other major cruise destinations in the Caribbean.

Industry giant Carnival plans to do away with a popular program that lets customers in the midst of a cruise get extra savings when they commit to another trip. Under the terms of the Future Carnival Vacations Program, passengers who deposit $100 for a future cruise while on board a vessel receive certificates worth up to $200 per cabin in on-board credits.
