Sorry, despite being a Hilton Diamond member, unless one wants to be in Puchong I can't see this hotel as a destination in itself.

The mall below the hotel is closed (0 shops), and getting out of the hotel on foot requires walking down a multi storey CAR ramp. For some reason, they couldn't carve out a portion from the closed mall to give pedestrians a chance.
Grab is really the only option to leave/enter even if you just wanted to get to the shophouses across the street.

It's cheap for a reason, and honestly for RM200+ still not cheap enough to draw me to Puchong for a stay.

The HGI's in KL are usally around RM150, and these are much better location wise for exploring KL. Rooms there are half the size, and there are noise issues but you get what you pay for.
