10/10
The resort is best for families. The water park is the star facility. My family enjoys the water park very much. There are other kids facilities which makes the resort to be the best for kids resort, according to my kids comments.
On the other hands, it is close to Gold Coast Light Rail, which makes it very accessible to other GC locations. There is a bus stop just out side the main entrance for Sea World. If you do not drive and take public transport, it is very accessible.
