This could be a tough one for you! I have found that on cruises, its more economical to "rent/trade" your points on this board, and then pay for your cruise with cash (you can save lots of points that way). You might want to think about cancelling the points res for 1 person in your party. Then you could use those extra points that you free up to upgrade the rest of your party. Then just pay cash for the person you had cancelled. Any excess points you have due to the cancellation, you can just rent on this board. You'll probably end up with some extra cash to boot! Hope that makes sense. Good luck!
