Not sure were CJH gets his info from re: kids staff are paid very well and have officer privleges?
I know 1st hand that the wages are not that great , and on some ships they do have officer status; which means they get to eat in the officers lounge.
The staff are very appreciative of tips and yes they do rely on them as well.
These are your children that you are entrusting them with. They love what they do, and they make your family trip extra special. Isn't that worth the tip? It has always been for our family. Hope this helps.
