Some helpful observation i made while in Malaysia
If your looking to get to Penang from West Coast i.e. Redang etc their are lots of Mini Van taxi's that do this for around 80RM per person.
Also Premiership football is on most of the smaller islands i.e. perhen and redang so dont threat :P
Cocohut Chalet was an ok place to stay but the beach next to it was very small and some contruction is on-going... not a great beach but the good news is they have many boat taxi's who take you to all the islands and pick you up for example Turtle Beach or Shark Bay etc (no sharks left) usually for 10RM to 15RM.
In KL most of the Taxi's charge 15RM to goto most local hotels if metered can be around 10RM but most wont bother because of the traffic so 15RM sounds reasonable.
