Just went 2 weeks ago. 1 day trip.

1. Can stay somewhere near awana sky. Then take cable care to and fro up.
2. Bring IC. The tickets are cheaper if u buy with Malaysian IC.
3. Outdoor theme park very long queue. U need to wait average 60 to 90 min for a 2 min ride. U can however, download an app and sign up for virtual queuing.
4. Food and drinks very costly. Cheaper to eat fast food. Eg pizza hut. A/W.
