DaleReid, if you're taking a cab outside a 5 star hotel, of course they are gonna try to rip you off. I have heard tourist telling me they paid xxx amount for a 10 minute ride.
What you can do is ask the hotel concierge, get them to tell you which is the shortest route to the destination, then you can tell the cab driver.
Most are honest. All cabs have meters, but most will turn them off at night and demand a one time off fee.
You can report them to the many tourist police around shopping complex in Kuala Lumpur.
Hope this helps.
Cheers.
