No. I did not write those words. I quoted from a travelogue entry by staffyandlyddy in Travelpod.com.
They also gave a breakdown of what they had to pay those ripp-off merchants to climb the mountain (for non-Malaysian):
Dorm Room at Park Headquarters – 85RM each
Permit to Climb Mt Kinabalu – 100RM each
Insurance (even though we have our own) – 7RM each
Guide – 85RM short trek / 100RM Long Trek – shared
Taxi from Park HQ to Start Point – 85RM – shared
Room on Laban Rata (halfway point) – 208RM each (including really poor meals)
Total cost (if climbing individually on short trek) – 555RM (111 Euro) for the 2 nights.
