I went there last week and many people especially China people.
1) bring more water (@14)
2) if you can, bring food your self (expensive inside the park)
3) if you go with baby, bring a trolley
4) bring hat and umbrella and small fan (very hot)
5) go up the hill to see the dolphine show and walk the shark acqurium asap as so many China people
6) Go the the Wet Wet side, you will have fun and suitable for kids as well
