Like other members had mentioned: Kuala Lumpur Convention Centre



I went there 2 weeks ago, I initially thought there is a parking entrance (the orange box I colored on the map above) there after reaching but only have drop-off point. I suggest if you have someone else to handle the kids while you drop the kids off there then you can head straight to the convention centre parking lot to park. But still, I wouldn't recommend this method because turning into Jalan Pinang from Jalan Perak (as shown at the starting point in my map) is kinda dangerous move, tried that once but luckily the traffic stopped for me to go through.

Follow the red line to go into convention centre parking. Once you get past the gate, you should be seeing seahorse symbol with a number on it, I forgot what number the seahorse symbol has.

By the way for heads up: if you want to redeem the free entry ticket for birthday month, make sure you only go there on WEEKDAYS. I went there with my gf on weekends and we kinda got scammed, the counter strictly mentioned only for weekdays while their social media promoted valid for any day of the month.
