I am planning to Malaysia this March so could you please provide me a rough eternery for Langkavi also provide local tour agency number if possible..Thanks in Advance
We are not travel agents so it is impossible to know what you want to do on your holiday and it is up to you to decide.
Start by looking under the green band at the top of the page where it says Things to Do. Get some ideas from there. Alternatively google will also help.
Once you have a rough itinerary, then we can help you to organise it better.
As mentioned Sachin , there is some great info on this site, research as much as you can find. As Steady has said come back when you have done your research.
Otherwise you will have to hire a travel agent in your home country to plan your trip.
