KL-Singapore

Let's start somewhere on familiar territory. One of the way to travel is via coach -which is one of the cheapest mode almost anywhere in the world!

So, you are in KL and want to travel to other parts of Malaysia or Singapore perhaps. Here are some guidelines:

Coaches in Malaysia
Here are some useful info on coaches that you can find. Since most travellers starts from Kuala Lumpur (capital of Malaysia - known to locals as KL), I shall start with coach/bus stations that you can find in KL.
The most famous coach terminal , the one that has all the coaches that goes to all part of Malaysia (all locals in KL will know):HENTIAN PUDURAYA - you can ask anyone in KL they will gladly tell you how to get there. Here you can get coaches at to almost anywhere you want with a very affordable price. But be warn that the place is rowdy and is full of people at anytime. Be careful with your belongings at all time - targets at foreigners are more common.
You can find taxis a plenty there. Always insist for the meter to be on.
Next is the Hentian Putra, Kuala Lumpur. It is near the Putra World Trade Centre (PWTC) on Jalan Putra. Nearby is The Mall, The Legend (hotel) ...you can ask me too for landmarks.
The buses here mostly go to the East Coast. If you are back packing to the islands such as Redang, Pulau Perhentian, Pulau Gemia etc this is the place for you to take your bus. But you still can take those at Puduraya aswell.
( I met once an English man of 60+ travelling back to KL from Redang...he said he spent 3 months there what he can spend 1 week in Gold Coast.... ).
Hentian Duta - near to some some government offices, Hockey Stadium and the Duta Tennis Court. Most buses from here goes up North. The common bus you can find is the Transnational coach. Like I mentioned, you can still get from Puduraya aswell.
Cons: Quite inaccesible. Need taxis to get in and out of this terminal.
Lastly, the Pekeliling Bus Station. Goes mostly to eastern side of Malaysia to Pahang etc. Goes to Raub, Kuantan, Jerantut.(Not that familiar with this stop. Anyone with more info please share!)
Now, there are also coaches known as executive coach which cost slightly more than the coaches that you can find on the bus stations that were mentioned. Most of these coaches are located at places that are easily accessible or near to shopping malls. These coaches mostly go down to Singapore.
Here are the names of the companies;
Aeroline - they go from various parts of KL/Selangor to Singapore as well as Penang. (They have a toilet for light usage and serve coffee/tea, onboard movies,sandwiches from Subway...value for money!You can buy the tickets online from anywhere in the world!But note their policy is strict but as long as you follow them, you are ok) .
Damai Ekspress - Pasar Rakyat to Singapore.
First Coach - various parts of KL to Singapore.
Nice - from KTMB (old railway station) to Singapore. (They have tvs, cold sandwiches )
Odyssey - KL to Singapore.
Transnational - Malaysian Tourism Centre, Jalan Ampang to Singapore.
