I've just come back 3 days ago. If you were visiting the water park and wants to watch the circus show afterwards, you can pay RM90 per head (adult/child). There are free shuttle bus to take you there.
One thing to recommend is to see the (free) Stunt Show at 3:30 or 8:00pm in the water park. Most stuntmen are Americans and Australians. It's like Hollywood or Warner Bros show overseas.
Hotel-wise, I found the service at Chateau Star River Hotel very good. Staff so caring and helpful. Breakfast, Dinner Buffet and A-lacarte standard very good, comparable to HK.
