Star kids joining fee is $10. Actually I find it not worth to join star kids. Star kids cruise for free only for full price cruises. Those 1 for 1 cruise (50% discount), star kids pay the same as adult, which is actually a better deal if you do the maths. For kids, just get the cheapest inside stateroom, they dont't know how to appreciate balcony or sea view anyway.
There is a child care centre, $8 an hour. I put my kids there for 1 hour everyday and they enjoy it very much. Then my mother and I can go casino
I planning a cruise.
