If you stay around Subang, then you still can visit this place 
On the other hand, swimming at 3k Subang on rainy days are quite scary... The water is freezing cold 
But now I'm kinda used to it so it shouldn't be a problem lolz...

I can't immediately swim once I enter the pool as I am afraid of cramps... Usually I will stay in the water for like 5 minutes before starting my laps 
There is a swimming academy called DSA at 3K as below:

They should have swimming classes for kids 

Hi. Trying my luck here. Anyone knows swimming lesson held by anyone in Kompleks 3K Subang Jaya? There's one which is DSA Swimming Academy but they informed the branch have stopped taking new student already.

Btw, its for my kids aged 3-7 yo.

Thanks!
