Find Your Cruise
I think you'll find they don't. Basically the rule of thumb is 2 full adult fare paying passengers per cabin and then up to 2 children in addition to that have a percentage off the fare. If you book early enough there are some great discounts. Also it's a great holiday for all of you as a single parent family, the kids whatever age will be well catered for, as you will. I personally am P+O bia.
