Just a 3 day stop over in Kuala Lumpur - not sure whether to stay right in the city or out at the Sunway with the water park.
Berjaya Time Square Theme Park is quite limited. More fast rides and some arcades. Not too many for young kids.
With young kids, the Sunway Theme Park would be more fun and healthy active (swimming as opposed to just sitting in a ride) and a wildlife park. There are young adult rides and activities available there too. There are 5 different sections, and you can pay for entrance to 1 or 2 or all sections. There are discounts for students, senior citizens, and different rates for locals & foreigners. Sunway Lagoon Theme park closes at 6pm and is closed on Tuesdays, except during school & public holidays. Check out the website for more details: http://www.sunwaylagoon.com/
Either place is connected to a shopping mall for evening activities and resting period. I would recommend Sunway Resort for you. about 5 years ago
