please have a look on the pictures I posted to assess suitability. hope this helps.
in general, this amusement park offers mild games, allowing small kids to ride and race on their own., nothing thrilling.however circuit challenge, racing karts on official racing course is cool, good for adults too.
actually the day we visited wasn't crowded. we bought circuit challenge tickets at ticketing booth , a couple of them around in the park, need not go to the official racing course as it is quite far away. you can check official website the closing time of circuit challenge. we joined it at around 12:15pm, the course was closed for amateur players at 1:15pm. so don't wait until the last minute, just in case you may want to play it again.
