Hi James
Taiping and Ipoh are in the state of Perak and so two days for both are ample. IMHO. Perhaps others would care to comment. Teluk Intan, also in Perak is worth exploring but quiet and a bit off the main highway.
I like Malacca. It is a place I would consider, after Penang and Butterworth. North of Butterworth is Alor Setar, Kedah. Almost as quiet as Teluk Intan. I must admit it has been a long time since I visited Teluk Intan but been to Kedah quite recently, so am happy to elaborate on Kedah. More Chinese people lives in Teluk Intan than in Kedah........Alor Setar/Kedah is populated with a heavier concentration of Malays.
Don't discount Kuantan. You may decide this is the place that you would like to move to. I think you need to get in touch with one of the expats who moved to Kuantan.
The thing about KL is that we tend to think of it as a rat race and concrete jungle and yet, there are lots of areas which may be appealing. Many, many years ago, my step father bought a place in Petaling Jaya. Back then, it was considered the end of the earth! How things change after a few decades! It kind of reminds me about this book that I stumbled across...................a story told in pictures without words but the message is so clear................that it sticks in my mind.
Picture a mother with her baby staring out of the window. They have moved into a quiet countryside area and far away, there is the city. You can barely see the blurred outline. Turn the page, mother and toddler still feel safe whilst they gazed at the emerging outline of the city. And, the next, there is mother and child of 5 years old, with the city creeping nearer. Turn another page............you get the gist of what I am trying to say here?
So, don't think KL but think suburbs. However, bear in mind that one day, this quiet suburb is going to become part of the KL city.
Just my two cents worth of opinions.
