I am amazed that this is not a more popular choice.
It’s easy to get to, and an easy place to enjoy. English is one of the two official languages (we Brits didn’t hand over until 1956), everyone speaks it and all the signs are dual language. The money is a simple decimal system and easy to understand.
If you want the wonders of a modern metropolis, with great architecture, huge malls and all the shopping you can stand, you’ve got it. If you want to see one of the greatest structures on earth, you’ve got it (the Petronas Twin Towers). If you want genuine jungle and rainforest to explore in a relatively safe way, you’ve got it. If you like wildlife and the chance to see some amazing creatures you probably won’t see anywhere else, you’ve got it. If you want idyllic beaches and the hedonistic, beach/party life, it’s all just an hour or so away from the city itself. If you want amazing landscape and natural formations, you’ve got it (the Batu Caves are an amazing natural feature). If you like buying fake Rolex watches and other counterfeit goods, this is your dream location (but you can ignore all that and steadfastly refuse to sponsor such brand name piracy if you wish, and of course this is what you should do).
It’s a safe, clean city. Friendly people. There are three major faiths and they all get along just fine, following the principle of “I’ll choose my way of life, you choose yours, now let’s just get on with things”. You can walk around the city at night without much of a problem. If you want to drink, you can. If you want to party, you can.
You will instantly feel like a millionnaire. Your spending power is dramatically increased as soon as you set foot in Malaysia. Just to give you one example, it’s perfectly feasible to hire a cab driver for the entire day if you want to! The driver will quite happily switch off the meter and drive you around to all of the main sights and attractions, wherever you want, all day, for less than $100. The kind of ‘luxury’ hotel that would cost an arm and a leg anywhere in the Western world is actually very affordable in Kuala Lumpur.
The weather is generally on the pleasant side of warm and dry, without it being too deadly tropical or intense. The ‘monsoon’ season is neither as focused nor as intense as it was a couple of decades ago. When I was there we had some of the early monsoon rain, and it didn’t stop any of the fun.
Lots of good food, from very safe, Western cuisine to traditional dishes served in the traditional way (such as veg and lamb curry on banana leaf, eaten Hindu style with your hands) (hands washed before and after).
It’s a really great place and more people should go there. Whatever sort of holiday experience you want, it can provide (except skiing, which admittedly is not their strong suit). And it’s all very, very cheap and affordable. In a smiling, safe, welcoming, warm, friendly country full of delights, wonders, beauty and good food. What are you waiting for?
