It's worth to note that there is this very weird rule for Park n' Ride, in order to qualify you have to fulfill certain criteria.

LRT / MRT hourly parking is usually expensive, but if you Park n' Ride LRT / MRT, it will usually be a flat rate of RM4.30. But here comes the kicker, in order to qualify for this flat rate, you have to ride at least 4 stations away from the station you parked at. Kinda defeats the purpose if you ask me.

So if you park in MRT Bandar Utama and step off MRT Pusat Bandar Damansara (3 stations away only), you are not eligible for the RM4.30 flat rate parking, kinda dumb if you ask me. You actually have to drive out to a further station with Park n' Ride to enjoy the flat rate.
