If you have young children, avoid the Aust/NZ cruise. Go to Royal Carribean instead. This ship is predominately retirees. Some of which are not very accepting of young children. You will be getting the evil eye, or rolling eye balls as soon as you kids open their mouth.
Kids club was amazing though. We left the kids there most of the time. They enjoyed it. You do have to pick them up for lunch and dinner.
We were a party of 3 adults between 30 - 38. There was hardly anything fun for us to do. Majority of the activities and music is catered towards the the older crowd.
